- Cystometry at different infusion rates was performed in 7 rats in vivo. The bladders were furthermore allowed to relax from different transmural pressures. When distension of the bladder was moderate, relative relaxation was small and almost independent of transmural pressure and infusion rate. When distended to large volumes, however, there was a marked increase in bladder wall relaxation and the relaxation increased with increasing infusion rates. These findings indicate the importance of standardization of the cystometric procedure

- INTRODUCTION: α1-Adrenoceptors are considered critical for the regulation of prostatic smooth muscle tone. However, previous studies suggested further α1-adrenoceptor functions besides contraction. Here, we investigated whether α1-adrenoceptors in the human prostate may activate extracellular signal-regulated kinases (ERK1/2). METHODS: Prostate tissues from patients undergoing radical prostatectomy were stimulated in vitro. Activation of ERK1/2 was assessed by Western blot analysis. Expression of ERK1/2 was studied by immunohistochemistry. The effect of ERK1/2 inhibition by U0126 on phenylephrine-induced contraction was studied in organ-bath experiments. RESULTS: Stimulation of human prostate tissue with noradrenaline (30 μM) or phenylephrine (10 μM) resulted in ERK activation. This was reflected by increased levels of phosphorylated ERK1/2. Expression of ERK1/2 in the prostate was observed in smooth muscle cells. Incubation of prostate tissue with U0126 (30 μM) resulted in ERK1/2 inhibition. Dose-dependent phenylephrine-induced contraction of prostate tissue was not modulated by U0126. CONCLUSIONS: α1-Adrenoceptors in the human prostate are coupled to ERK1/2. This may partially explain previous observations suggesting a role of α1-adrenoceptors in the regulation of prostate growth.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Primary objective: to investigate if 30-MINUTES-TUMT can be performed under topical anesthesia and analgesics. Secondary objectives: to evaluate retrospectively analgesics and to study parameters connected with pain. Materials and Methods: Eighty-nine patients underwent TUMT. Patients were divided into four groups with different medications. Paracetamol and tolterodin-L-tartrate were administered in all groups. The first group was also given hydromorphone hydrochloride and atropine sulphate, the second group dextropropoxyphene, the third group morphine and diclofenac, and the fourth group morphine and dextropropoxyphene. Pain during TUMT was registered using the VAS scale. Results: Pain during TUMT was (VAS in mm), respectively, total-first-second-third-fourth group: at 5 min -30, 31, 12, 28, 35; at 15 min -30, 23, 16, 25, 34; at 25 min -30, 28, 18, 25, 35. All patients accepted the treatment. No significant difference between the different drug schedules was noticed. Conclusions: It is possible to treat patients with 30-MINUTES-TUMT with local anesthesia and analgesics. The pain can be accepted by all patients.

Glycine 1.5% for Irrigation Should Be Abandoned
- 2013

Forskningsöversikt (refereegranskat)abstract
- Background: Glycine 1.5% has long maintained a dominating role as an irrigating solution for monopolar transurethral resection of the prostate (TURP), as well as for certain other transurethral procedures. Materials and Methods: This review summarizes the findings of systematic experimental and clinical studies in which glycine 1.5% for irrigation was infused/absorbed and the outcome compared to at least one other irrigating fluid, including the isotonic saline used for bipolar TURP. Results: There were 11 studies in animals, 3 in volunteers and 6 in patients undergoing TURP. With only one exception, which is probably due to low power, these studies either show a poorer outcome after administration or absorption of glycine solution or else that glycine 2.2% is more toxic than glycine 1.5%. The poorer outcomes consisted of more tissue damage or higher mortality (animals) or more symptoms (volunteers and patients). Conclusion: The safety of monopolar TURP would be improved by replacing glycine 1.5% with some other electrolyte-free fluid. The author argues that glycine 1.5% should be abandoned completely.

"He Gave Us the Cornerstone of Sexual Medicine": A Nobel Plan but No Nobel Prize for Eugen Steinach
- 2020
-

Tidskriftsartikel (refereegranskat)abstract
- This paper reviews the files in the archive of the Nobel Prize Committee for Physiology or Medicine on the Austrian physiologist and pioneering researcher in the emerging fields of urology and sexual medicine: Eugen Steinach (1861–1944). It reconstructs and analyzes why and by whom Steinach was nominated for the Nobel Prize between 1920 and 1938 and discusses the reasons why he never received the award, although the Nobel Committee judged him as prizeworthy. Steinach’s Nobel nominee career is extraordinary – not only because of his strong support by renowned international nominators from different scientific and medical disciplines, but also because of the controversial discussions within the Nobel Committee on his achievements, colored by the debates in the international scientific community. The Nobel Prize story adds a new perspective on how contemporary international scholars evaluated Steinach’s research on reproduction, “male-making” females, “female-making” males, homosexuality, and the concept of rejuvenation.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this study in a small group of non-stone-forming Chinese persons was to measure the levels of supersaturation with calcium oxalate and calcium phosphate and pH with the aim of confirming if any of the different short-term urine samples were better for risk evaluation than a 24-h sample. Nine normal men and 1 woman collected urine during 4 periods of the day. <i>Period 1</i> between 08 and 12 h, <i>Period 2</i> between 12 and 18 h, <i>Period 3</i> between 18 and 22 h, and <i>Period 4</i> between 22 and 08 h. Each sample was analysed for calcium, oxalate, citrate, magnesium and phosphate, and estimates of supersaturation with calcium oxalate (CaOx) and calcium phosphate (CaP) were expressed in terms of AP(CaOx) and AP(CaP) index. An estimate of the solute load of CaOx was also calculated. Urine composition for 24-h urine (<i>Period 24</i>) was obtained mathematically from the analysed variables. Urine composition corresponding to 14-h urine portions 22–12 h (<i>Period 14</i>N) and 08–22 h (<i>Period 14 D</i>) were calculated. The lowest pH levels were recorded in <i>Period 1</i> urine. The highest level of AP(CaOx) index was recorded during <i>Period 1</i>, and the product AP(CaOx) index × 10<sup>7</sup> × hydrogen ion concentration was significantly higher in Period 1 urine than in 24-h urine (<i>p</i> = 0.02). Also, the product SL(CaOx) × 10<sup>7</sup> × hydrogen ion concentration was significantly higher in <i>Period 1</i> urine (<i>p</i> = 0.02). Low AP (CaP) index levels were recorded in <i>Period 4</i>, but also in all periods following dietary loads of calcium and phosphate. With the important reservation that the analytical results were obtained from non-stone-forming persons, the conclusion is that analysis of urine samples collected between 08 and 12 h might be an alternative to 24-h urine. The risk evaluation might advantageously be expressed either in terms of the product AP(CaOx) index × 10<sup>7</sup> × hydrogen ion concentration or the product SL(CaOx) × 10<sup>7</sup> × hydrogen ion concentration.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: We aimed to evaluate the general status of last-year residents in Turkey by filling in the questionnaire Evaluation of Residencies in Europe. Subjects and Methods: The questionnaire `Evaluation of Residencies in Europe, designed by the European Society of Residents in Urology (ESRU), was applied to 91 last-year urology residents. It consisted of 7 sections; Introduction, Membership, Residency, Life and Financial Conditions, Future Practice, Training and Research Activities and Contribution to Scientific Literature. The results were determined and reviewed as well. Statistical analysis was performed using ANOVA and the Kruskal-Wallis Test. Results: More than 40 parameters were evaluated. The level of English was average or good for 86%. Half of the residents were aware of ESRU activities, 91% knew national ESRU representatives. Fifty-seven percent of the residents wanted to subspecialize in urology, nephrectomy or andrology, and general urology procedures had a high rate being performed by a first surgeon. Transurethral prostate resection, transurethral resection of bladder and extracorporeal shock wave lithotripsy were well known, with a rate of 76%. Conclusions: Although the Turkish resident number is one of the most excessive in Europe, we have a well-trained homogenous resident group especially in the field of endourology; most of those in the last year of their training period were satisfied with their general condition.

Experimental partial ureteric obstruction in newborn rats. X. Renal function and morphology after unobstruction

Tidskriftsartikel (refereegranskat)abstract
- Partial obstruction of the left ureter was created in newborn rats. Unobstruction was performed after 2 or 7 days. The investigations were carried out at 9 weeks of age – under slight hydropenia to institute an element of stress. Unobstruction was successful. On the <i>unobstructed</i> side, there were nevertheless impairments as compared to controls: urine osmolality (–32%), free water reabsorption (–44%), potassium excretion (–34%), renal blood flow (–36%) and glomerular filtration (–36%). On the <i>intact contralateral</i> side, tubular changes were the only signs of an attempt to compensate. Thus, consistent renal damage remained despite a very early unobstruction. Furthermore, the changes were similar to those we observed during long-term <i>permanent</i> obstruction. The injury seems to be established within a very short time and imitates the probable development seen in the affected fetus: after start of production, the urine is confronted by the preformed obstruction at the pyeloureteral junction. A high-pressure-prone system is built up and is not reversed, until the pelvis has become dilated and thus capable to buffer urinary flow peaks. Thereafter, no further deterioration occurs except in specific conditions. If clinically applicable, these observations implicate that there is no advantage with surgical intervention, even when performed early in fetal life, and there is no need for swift intervention, as the damage does not progress after its establishment. Most of the cases probably do not require surgery at all, unless pain, obvious functional impairment or urinary tract infection supervene.

Tidskriftsartikel (refereegranskat)abstract
- Background: Rising serum levels of prostate-specific antigen (PSA) after radical prostatectomy are indicative of recurrent prostate cancer. This double-blind, placebo-controlled phase II study evaluated the anti-tumour activity of the anti-epithelial cell adhesion molecule (EpCAM) antibody adecatumumab in delaying biochemical disease progression. Patients and Methods: Prostate cancer patients with increasing serum PSA levels following radical prostatectomy were randomized to low- (2 mg/kg) or high-dose adecatumumab (6 mg/kg) or placebo. The primary efficacy endpoint was the mean change from baseline in total serum PSA at week 24. Secondary endpoints included PSA response rate, prolongation of serum PSA doubling time and time to biochemical disease progression. Results: The primary and secondary endpoints of the study were not met in the predefined analyses. In a retrospective analysis of patients with baseline PSA <= 1 ng/ml and a high EpCAM expression, both the mean increase in PSA from baseline to week 24 and the PSA doubling time at week 15 were significantly improved in the high-dose adecatumumab group compared with the placebo group. Most frequent treatment-related clinical adverse events were gastrointestinal (diarrhoea and nausea) or general events (chills), showing a dose dependency but no grade 3/4 intensity in any patient. Conclusion: In men with rising PSA levels after radical prostatectomy and no evidence of clinical relapse, adecatumumab delayed disease progression in a subgroup of patients with baseline PSA levels <= 1 ng/ml and high EpCAM-expressing tumours.

- Air guns are known as low-velocity arms and are considered harmless. However, injuries from air weapons can be serious and even fatal, particularly in children. We present a potentially life-threatening penetrating retroperitoneal injury of a 3-year-old boy caused by an air gun, and the successful removal of the bullet via a laparoscopic approach. The patient was brought to our center with a penetrating air gunshot wound on his right side in the waist area. He was accidentally shot by his brother at their home. The patient’s clinical condition was stable. Computed tomography scan showed the bullet in the retroperitoneum near the inferior vena cava. A three-port laparoscopic transperitoneal approach was performed. The bullet was found just 0.5 cm caudal to the right renal hilum and 0.5 cm near the inferior vena cava; it was then removed. Operation time was 42 min and the postoperative course was uneventful. Thanks to improvements in laparoscopic surgical techniques, laparoscopy has become a feasible and effective treatment modality even for the removal of foreign bodies in children.

Forskningsöversikt (refereegranskat)abstract
- Due to the lack of disease-specific symptoms, diagnosis and follow-up of bladder cancer has remained a challenge to the urologic community. Cystoscopy, commonly accepted as a gold standard for the detection of bladder cancer, is invasive and relatively expensive, while urine cytology is of limited value specifically in low-grade disease. Over the last decades, numerous molecular assays for the diagnosis of urothelial cancer have been developed and investigated with regard to their clinical use. However, although all of these assays have been shown to have superior sensitivity as compared to urine cytology, none of them has been included in clinical guidelines. The key reason for this situation is that none of the assays has been included into clinical decision-making so far. We reviewed the current status and performance of modern molecular urine tests following systematic analysis of the value and limitations of commercially available assays. Despite considerable advances in recent years, the authors feel that at this stage the added value of molecular markers for the diagnosis of urothelial tumors has not yet been identified. Current data suggest that some of these markers may have the potential to play a role.in screening and surveillance of bladder cancer. Well-designed protocols and prospective, controlled trials will be needed to provide the basis to determine whether integration of molecular markers into clinical decision-making will be of value in the future.

Tidskriftsartikel (refereegranskat)abstract
- <b><i>Introduction:</i></b> Hyperthermic mitomycin (HM) is a novel treatment modality for selected patients with high-risk non-muscle invasive bladder cancer (NMIBC). We sought to determine predictors of response to this therapy. <b><i>Patients and Methods:</i></b> A longitudinal, cohort study of 97 patients with high-risk NMIBC treated with ≥4 HM instillations on a prophylactic schedule was conducted. The primary outcome was time-to-progression survival; secondary outcomes were overall survival, cancer-specific survival, and adverse events. Descriptive statistics, Kaplan-Meier survival analyses, Cox proportional hazards modelling, and univariate and multivariable regression were performed. <b><i>Results:</i></b> The presence of initial complete response (CR; no evidence of disease at first check video-cystoscopy and urine cytology) post-HM treatment was an independent predictor of good response to HM. Female patients and those without carcinoma in situ (CIS) also appeared to respond better to the intervention. The overall bladder preservation rate at a median of 27 months was 81.4%; 17/97 (17.5%) patients died during the course of the study. <b><i>Conclusions:</i></b> High-risk NMIBC patients can be safely treated with HM and have good oncological outcome. However, those without an initial CR have a poor prognosis and should be counselled towards adopting other treatment methodologies such as cystectomy. Female gender and lack of CIS may be good prognostic indicators for response to HM.

- Surgery has the potential to disseminate cancer cells, and we therefore hypothesized that extensive transurethral resections of the prostate (TURP) would be followed by a worse prognosis than minor ones. For this purpose, the association between the extent of surgery, disease progression, and mortality was studied in 138 patients with prostatic cancer who had undergone TURP. The results show that a large bleed (≥275 ml) indicated a slightly increased relative risk of general progression of the cancer (relative risk (RR) = 1.9, 95% confidence interval (CI) = 0.9–4.1) and death (RR = 1.5, CI = 0.6–3.3). Other parameters of extensive surgery, such as the operating time and fluid absorption, were not associated with increased risk. Patients with a medical disease, however, such as hypertension and congestive heart failure, had a significantly higher relative risk of general progression (RR = 2.7, CI = 1.2–6.1) and death from prostatic cancer (RR = 4.6, CI = 2.0–10.7) in addition to an increased relative risk of death from other causes (RR = 3.7, CI = 1.3–10.5). We conclude that concurrent medical disease, but not an extensive TURP, worsened the prognosis of patients with prostatic cancer who underwent TURP.
