- Background: There is limited information on the distribution of retroperitoneal lymph node metastases (LNMs) in upper tract urothelial carcinoma (UTUC).Objective: To investigate the location of LNMs in UTUC of the renal pelvis or proximal ureter and short-term complications after radical nephroureterectomy (RNU) with lymph node dissection (LND).Design, setting, and participants: This was a prospective Nordic multicenter study (four university hospitals, two county hospitals). Patients with clinically suspected locally advanced UTUC (stage >T1) and/or clinical lymph node–positive (cN+) disease were invited to participate. Participants underwent RNU and fractionated retroperitoneal LND using predefined side-specific templates.Outcome measurements and statistical analysis: The location of LNMs in the LND specimen and retroperitoneal lymph node recurrences during follow-up was recorded. Postoperative complications within 90 d of surgery were ascertained from patient charts. Descriptive statistics were used.Results and limitations: LNMs were present in the LND specimen in 23/100 patients, and nine of 100 patients experienced a retroperitoneal recurrence. Distribution per side revealed LNMs in the LND specimen in 11/38 (29%) patients with right-sided tumors, for whom the anatomically larger, right-sided template was used, in comparison to 12/62 (19%) patients with left-sided tumors, for whom a more limited template was used. High-grade complications (Clavien grade ≥3) within 90 d of surgery were registered for 13/100 patients. The study is limited in size and not powered to assess survival estimates.Conclusions: The suggested templates that we prospectively applied for right-sided and left-sided LND in patients with advanced UTUC included the majority of LNMs. High-grade complications directly related to the LND part of the surgery were limited.Patient summary: This study describes the location of lymph node metastases in patients with cancer in the upper urinary tract who underwent surgery to remove the affected kidney and ureter. The results show that most metastases occur within the template maps for lymph node surgery that we investigated, and that this surgery can be performed with few severe complications.

- Objective: To report population-based clinical presentation and outcomes in patients with urosymphyseal fistula (USF) after pelvic radiotherapy (RT).Patients and methods: A retrospective chart review was performed in 33 consecutive patients diagnosed with suspicion of USF in a tertial referral center from 2014–2022 to ascertain information about diagnostic delay, clinical presentation, precipitating causes, treatments received and outcomes during the median 22 months follow-up. Out of 33 consecutive patients with suspicion of USF, one female with vesicovaginal fistula, one patient developing RT-associated bladder angiosarcoma, four patients with short follow-up (<3 months), and three patients that during chart review not were considered to have a USF were excluded.Results: In all, 24 males with a median age of 77 years were diagnosed with USF. Local pain was the predominating symptom in 17/24 (71%) patients. Endourologic manipulations preceded the diagnosis of USF in 16 patients. Five patients had a diagnostic delay of more than 3 months. At diagnosis, 20/24 patients had radiological signs of osteomyelitis, and five had a concomitant rectourethral fistula. Due to comorbidity, five patients were not amenable to any other interventions than urinary catheter or suprapubic tube in conjunction with long-term antibiotics, of which three died from infections related to the USF. Out of the remaining 19 patients receiving some form of urinary diversion, five had recurrent osteomyelitis, of which four did not undergo cystectomy in conjunction with surgery for the USF.Conclusions: Urethral endourologic interventions in patients previously subjected to pelvic RT should be performed cautiously.

Tidskriftsartikel (refereegranskat)abstract
- Objective: The aim of this study was to present early outcome data for patients treated for penile cancer with organ-sparing reconstructive surgery at two referral centres in Sweden.Material and methods: Oncological, cosmetic and functional outcome and complications were analysed retrospectively during the period 2011-2013. Twelve patients with non-invasive penile cancer were treated with glans resurfacing (GR), while 15 patients with invasive penile cancer underwent total glansectomy with neoglans reconstruction (TGN).Results: The 12 patients treated with GR had a median age of 66 years (range 35-83 years) and a median follow-up time of 16 months (range 4-40 months). All patients showed carcinoma in situ and negative surgical margins in the final pathology report. The 15 patients treated with TGN had a median age of 71 years (range 37-78 years) and the median follow-up time was 10 months (range 1-25 months). All patients had invasive penile cancer and the surgical margins were negative in all cases except one. Complications occurred in five of the 27 patients (18%), and in most cases these were minor and infection related. No recurrences were seen in either group during follow-up, and all patients except one, who had undergone GR, were satisfied with the functional and cosmetic results.Conclusions: GR and TGN seem to be oncologically safe procedures for treating carefully selected patients with penile cancer, and the functional and cosmetic results are promising. Based on these findings, the authors recommend that penile amputation should only be carried out in patients who are not suitable for organ-sparing reconstructive surgery.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To prospectively assess anorectal dysfunction using patient-reported outcomes using validated questionnaires, manovolumetry and endoanal ultrasound before and 12 months after RC. Patients and methods: From 2014 to 2019, we prospectively included 44 patients scheduled for RC. Preoperatively and 12 months after surgery, 41 patients filled in a low anterior resection syndrome score (LARS-score) to assess fecal incontinence, increased frequency, urgency and emptying difficulties and a St Mark’s score to assess fecal incontinence in conjunction with manovolumetry and endoanal ultrasound examinations. Pre- and postoperative patient-reported anorectal dysfunction were assessed by LARS-score and St Marks’s score. At the same time-points, anorectal function was evaluated by measuring mean anal resting and maximal squeeze pressures, volumes and pressures at first desire, urgency to defecate and maximum toleration during manovolumetry. Wilcoxon's signed rank test was used to compare pre- and postoperative outcomes by questionnaires. Results: Postoperatively 6/41 (15%) patients reported flatus incontinence assessed by the LARS-questionnaire, and correspondingly the St Mark’s score increased postoperatively. The median anal resting pressure decreased from 57 mmHg preoperatively to 46 mmHg after RC, but without any postoperative anatomic defects detected by endoanal ultrasound. Volumes and pressures at first desire, urgency to defecate and maximum toleration during manovolumetry all increased after RC, indicating decreased postoperative rectal sensation, as rectal compliance was unaltered. Conclusions: Postoperative flatus incontinence is reported by one out of seven patients after RC, which corresponds to decreased anal resting pressures. The finding of decreased rectal sensation might also contribute to patient-reported symptoms and anorectal dysfunction after RC.

- Objective: Functional outcomes after ileal bladder substitution reflect the expectations of future patients at a particular centre. The aim of this study was to use validated questionnaires and a pad-weighing test to investigate functional outcomes after neobladder reconstruction at long-term follow-up in patients at a single centre. Materials and methods: During 2005 − 2015, 75 patients received a Studer ileal bladder substitute at the Department of Urology, Malmö. Forty-six of these patients were alive for follow-up and were evaluated using the pad-weighing test and the International Consultation on Incontinence Questionnaire–Urinary Incontinence Short Form (ICIQ-UI-SF), the Female Sexual Function Index (FSFI) and the International Index of Erectile Function (IIEF). Results: Five of 37 evaluable patients (14%) were considered fully continent, reporting a pad-weighing test result of 0 g and an ICIQ-UI-SF score of 0. The median ICIQ-UI-SF score was 8 [interquartile range (IQR) 3–11], and seven patients (17%) were continent according to the ICIQ-UI-SF score only. In the pad-weighing test, 28 out of 37 patients (76%) reported 0 g day-time leakage whereas only 12 out of 37 patients (32%) reported 0 g night-time leakage. At follow-up, nine out of 39 (23%) of evaluable male patients were potent. The median ICIQ-UI-SF score was significantly lower during the second half of the study period [4 (IQR 0–8) vs 10 (IQR 6–14); p = .003]. The inverse applied to the median IIEF score [5 (IQR 3–12) vs 2 (IQR 1–4); p = .02]. Conclusions: Functional outcomes at long-term follow-up after radical cystectomy and Studer ileal bladder substitute were at best modest in this series. Better outcomes during the second half of the study period might be explained by improved patient selection and a refined surgical technique, but possibly also by longer follow-up of patients during the first half of the period resulting in a more pronounced time-dependent decline in functional outcomes.

- BACKGROUND: Parastomal hernia (PSH) after urinary diversion with ileal conduit is frequently a clinical problem.OBJECTIVE: To investigate whether a prophylactic lightweight mesh in the sublay position can reduce the cumulative incidence of PSH after open cystectomy with ileal conduit.DESIGN, SETTING, AND PARTICIPANTS: From 2012 to 2017, we randomised 242 patients 1:1 to conventional stoma construction (n = 124) or prophylactic mesh (n = 118) at three Swedish hospitals (ISRCTN 95093825).OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was clinical PSH, and secondary endpoints were radiological PSH assessed in prone position with the stoma in the centre of a ring, parastomal bulging, and complications from the mesh.RESULTS AND LIMITATIONS: Within 24 mo, 20/89 (23%) patients in the control arm and 10/92 (11%) in the intervention arm had developed a clinical PSH (p = 0.06) after a median follow-up of 3 yr, corresponding to a hazard ratio of 0.45 (confidence interval 0.24-0.86, p = 0.02) in the intervention arm. The proportions of radiological PSHs within 24 mo were 22/89 (25%) and 17/92 (19%) in the two study arms. During follow-up, five patients in the control arm and two in the intervention arm were operated for PSH. The median operating time was 50 min longer in patients receiving a mesh. No differences were noted in proportions of Clavien-Dindo complications at 90 d postoperatively or in complications related to the mesh during follow-up.CONCLUSIONS: Prophylactic implantation of a lightweight mesh in the sublay position decreases the risk of PSH when constructing an ileal conduit without increasing the risk of complications related to the mesh. The median surgical time is prolonged by mesh implantation.PATIENT SUMMARY: In this randomised report, we looked at the risk of parastomal hernia after cystectomy and urinary diversion with ileal conduit with or without the use of a prophylactic mesh. We conclude that such a prophylactic measure decreased the occurrence of parastomal hernias, with only a slight increase in operating time and no added risk of complications related to the mesh.

Tidskriftsartikel (refereegranskat)abstract
- It is generally recommended to refrain from taking rectal biopsies in radioproctopathy. Herein we describe the clinical characteristics of urorectal fistulas after such biopsies in five patients. Conservative treatment is rarely successful. Diagnostic difficulties and comorbidities limiting the possibilities for radical surgical treatment options (i e pelvic exenteration) for urorectal fistulas are discussed.

- 2019
-
Ingår i: Scandinavian Journal of Urology. - : Medical Journals Sweden AB. - 2168-1805 .- 2168-1813. ; 53:2-3, s. 109-115

Tidskriftsartikel (refereegranskat)abstract
- Objective: In non-muscle-invasive bladder cancer (NMIBC), local recurrence after transurethral resection of the bladder (TURB) is common. Outcomes vary between urological centres, partly due to the sub-optimal surgical technique and insufficient application of measures recommended in the guidelines. This study evaluated early recurrence rates after primary TURB for NMIBC before and after introducing a standardized treatment protocol. Methods: Medical records of all patients undergoing primary TURB for NMIBC in 2010 at Skåne University Hospital, Malmö, Sweden, were reviewed. A new treatment protocol for NMIBC was defined and introduced in 2013, and results documented during the first year thereafter were compared with those recorded in 2010 prior to the intervention. The primary endpoint was early recurrence at first control cystoscopy. Comparisons were made by Chi-square analysis and Fisher’s exact test. Recurrence-free survival (RFS) in the two cohorts was also investigated. Results: TURB was performed on 116 and 159 patients before and after the intervention, respectively. The early recurrence rate decreased from 22% to 9.6% (p = 0.005) at the first control cystoscopy after treatment. Residual/Recurrent tumour at the first control cystoscopy after the primary TURB (i.e. at second-look resection or first control cystoscopy) decreased from 31% to 20% (p = 0.038). The proportion of specimens containing muscle in T1 tumours increased from 55% to 94% (p < 0.001). RFS was improved in the intervention group (HR = 0.65, CI = 0.43–1.0; p = 0.05). Conclusions: Introduction of a standardized protocol and reducing the number of surgeons for primary treatment of NMIBC decreased the early recurrence rate from 22% to 9.6% and lowered the recurrence incidence by 35%.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Studies suggest that a hybrid indocyanine green (ICG)-99mTc-nanocolloid tracer improves sentinel node (SN) identification compared to conventional dynamic sentinel node biopsy (DSNB).OBJECTIVE: To investigate hybrid tracer-guided SN identification in a multicentre setting and determine false-negative (FN) and complication rates.DESIGN, SETTING, AND PARTICIPANTS: A total of 130 patients with penile cancer scheduled for DSNB were prospectively included between February 2016 and December 2017 at two national Swedish referral centres. ICG-99mTc-nanocolloid hybrid tracer was used in the standard DSNB protocol.INTERVENTION: SNs were identified intraoperatively using radioguidance, fluorescence imaging, and blue dye.OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The number of SNs identified by each tracer and the rates of complications and nodal recurrence during median follow-up of 34 mo were recorded. Differences in proportions between groups were compared using χ2 and McNemar's tests.RESULTS AND LIMITATIONS: Overall, 453 SNs were identified preoperatively via single-photon emission computed tomography/computed tomography. Among the 425 SNs excised, radioguidance, fluorescence, and blue dye identified 414 (97%), 363 (85%), and 349 (82%), respectively. Fluorescence imaging helped to detect six SNs that were negative using the other tracers, two of which were from the same patient and contained metastases. Histopathological examination detected 33 metastatic SNs in 20/130 patients (15%). The FN rate was 12% per groin (95% confidence interval 8-16%).CONCLUSIONS: Identification of SNs in patients with penile cancer relies mainly on radioguidance, while fluorescence (ICG) and blue dye methods for optical SN identification are comparable. However, the value of fluorescence imaging should be further evaluated in studies with long-term follow-up.PATIENT SUMMARY: In this study, we investigated addition of a dye called indocyanine green (ICG) for assessment of lymph nodes in patients with cancer of the penis. ICG did not improve the rate of detection of nodes most likely to harbour cancer because of their location in the drainage pathway for lymphatic fluid, but did help in identifying additional metastases.
