  • A challenging review of childhood incontinence: rare complications of dysfunctional elimination syndrome in an epileptic boy.
  • 2011
  • Ingår i: The Turkish journal of pediatrics. - 0041-4301. ; 53:1, s. 100-3
  • Tidskriftsartikel (refereegranskat)abstract
    • A multidisciplinary approach is mandatory in defining the cause and directing the treatment of childhood urinary incontinence. Both pediatricians and pediatric urologists should carefully evaluate a child with incontinence for possible overlapping etiologies, before labeling him or her as a refractory case. We report an epileptic boy with dysfunctional elimination syndrome (DES) with associated rare complications of giggle incontinence and idiopathic urethritis, proving the need for a good voiding diary, patient history and structured symptom scores.

  • Does the diameter of dextranomer microspheres affect the success in endoscopic treatment of vesicoureteral reflux?
  • 2012
  • Ingår i: Urology. - 1527-9995. ; 80:3, s. 703-6
  • Tidskriftsartikel (refereegranskat)abstract
    • To evaluate whether the polymer microsphere diameter affects the success rate in the endoscopic treatment of vesicoureteral reflux.In our consecutive series, 56 patients underwent subureteral injection with Dexell and 60 patients were treated with Deflux. Patients were evaluated with pediatric lower urinary tract scoring system, uroflowmetry, and a residual urine volume and voiding diary at the time of injection and control. Patients with grade V reflux, duplex systems, paraureteral diverticula, or refractory lower urinary tract symptoms were excluded. The numbers of renal units with grade II-III vesicoureteral reflux were 78 and 73 in the first (Deflux) and second (Dexell) groups, respectively. The numbers of renal units with grade IV reflux were 24 and 17 in the first and second groups, respectively. The resolution rate was determined by voiding cystourethrogram at the third postoperative month. Postoperative febrile urinary tract infections and de novo scars in dimercaptosuccinic acid were noted. Groups were compared by the χ(2) test.Mean follow-up time and mean age of the children were not significantly different. The number of nondilating and dilating renal units was not significantly different. Resolution rates were similar between the groups (79.5 and 78%, respectively). There was no significant difference in terms of resolution rates when dilating and nondilating urinary systems were separately analyzed. The average volumes used per renal unit were 0.9 and 1.6 mL in the first and second groups, respectively (P < .005). Postoperative febrile urinary tract infection and de novo scar formation rates were similar.The diameter of dextranomer microsphere does not affect the short-term success rate in endoscopic treatment of vesicoureteral reflux. Multicentric, randomized and prospective studies are required for long-term clinical results.

  • Effectiveness of doxazosin in treatment of distal ureteral stones in children.
  • 2009
  • Ingår i: The Journal of urology. - 1527-3792. ; 182:6, s. 2880-4
  • Tidskriftsartikel (refereegranskat)abstract
    • We evaluated the effectiveness of doxazosin in children with distal ureteral stones in terms of stone expulsion rates and time to expulsion.A total of 39 patients 2 to 14 years old with lower ureteral stones smaller than 10 mm were enrolled and randomly divided into 2 groups. Group 1 consisted of 20 controls receiving ibuprofen for pain and group 2 consisted of 19 patients receiving doxazosin. Doxazosin dose was approximately 0.03 mg/kg daily. All patients were evaluated with x-ray, ultrasound or spiral computerized tomography. Stone expulsion rates and time to expulsion between the groups were compared. Mean followup was 19 days. Effects of doxazosin were also evaluated by comparing subgroups with stones smaller than 5 mm and 5 to 10 mm. Results were also evaluated with special emphasis on gender and age.Expulsion was observed in 14 patients (70%) in group 1 and 16 (84%) in group 2 (p >0.05). Mean expulsion times for groups 1 and 2 were 6.1 and 5.9 days, respectively (p >0.05). Although fewer pain episodes were observed in the treatment group, this finding could not be evaluated objectively. None of the patients experienced any adverse effects.Administration of 0.03 mg/kg doxazosin daily in children to treat distal ureteral stones up to 10 mm is not superior to analgesic alone. This result is not affected by gender, stone size or patient age. However, additional randomized controlled studies, especially including larger stone volumes, and different doses of doxazosin and other alpha-blockers, might highlight the usefulness of alpha-blockers for ureteral stones in children.

  • Near infrared spectroscopy to diagnose experimental testicular torsion: comparison with Doppler ultrasound and immunohistochemical correlation of tissue oxygenation and viability.
  • 2012
  • Ingår i: The Journal of urology. - 1527-3792. ; 187:2, s. 744-50
  • Tidskriftsartikel (refereegranskat)abstract
    • Near infrared spectroscopy measures tissue oxygenation even when there is complete cessation of blood flow. We evaluated near infrared spectroscopy to diagnose testicular torsion and blindly compared its accuracy with that of Doppler ultrasound. We also compared it by immunohistochemical evaluation of hypoxia and cell viability.Rats were randomized to 4 groups, including group 1-720-degree unilateral torsion, group 2-360-degree unilateral torsion, group 4-sham operation and group 4-720-degree unilateral torsion followed by surgical torsion reduction at minute 180. Near infrared spectroscopy and Doppler ultrasound were done blindly at minutes 0, 5, 30, 60, 180 and 400. All torsed and contralateral testicles were excised for pathological examination using hypoxia inducible factor-α for hypoxia and the TUNEL test for apoptosis. We compared all groups with the contralateral testis and the sham operated group.All blinded, near infrared spectroscopy measurements correctly identified the torsed testis after minute 5. Median oxygen saturation in groups 1 and 2 was significantly different compared to that in the sham operated group after minute 5. In group 4 near infrared spectroscopy detected detorsion with the loss of a significant oxygen saturation difference between the affected and the contralateral testicle after detorsion. At minute 400 median oxygen saturation in group 4 was not statistically different compared to that in the sham operated group (p = 0.09) but it was significantly different compared to that in groups 1 and 2 (p <0.001). In each torsed testis oxygen saturation was at least 18.75% lower than in the contralateral testis. In groups 1 and 2 hypoxia inducible factor-α staining in torsed testicles was significantly greater than that in the contralateral organ and the sham operated group. In group 4 hypoxia inducible factor-α staining after detorsion was significantly decreased compared to that in groups 1 and 2. There was no significant difference in the apoptotic index between the experimental and the contralateral testis or the sham operated group.Near infrared spectroscopy is as effective but quicker than Doppler ultrasound for detecting testicular torsion without a radiologist. Near infrared spectroscopy accurately reveals oxygen saturation, which is more vital than blood flow, on which Doppler ultrasound focuses.

  • Ochoa syndrome: a spectrum of urofacial syndrome.
  • 2010
  • Ingår i: European journal of pediatrics. - 1432-1076. ; 169:4, s. 431-5
  • Tidskriftsartikel (refereegranskat)abstract
    • The urofacial syndrome, also known as Ochoa syndrome, is a rare autosomal recessive condition that occurs in both genders and characterized by uropathy and facial abnormalities. Early diagnosis is crucial for the management and prognosis of urinary problems due to a dysfunctional bladder. We report 11 patients with urofacial syndrome in five families from Turkey with a median follow up of 32 months (range, 2-44 months).

  • Predictors of surgical outcome in children with vesicoureteral reflux associated with paraureteral diverticula.
  • 2010
  • Ingår i: Urology. - 1527-9995. ; 76:1, s. 209-14
  • Tidskriftsartikel (refereegranskat)abstract
    • To retrospectively evaluate success rates of different surgical approaches in the treatment of paraureteral (Hutch) diverticula (PUD) associated with vesicoureteral reflux (VUR) and also to define preoperative objective criteria to predict the surgical outcome.Records of 51 patients who underwent surgical treatment for PUD were reviewed. Intravesical ureteroneocystostomy (UNC), subureteral injection, and extravesical UNC were performed in 23, 28, and 10 renal units, respectively. Records of patients were evaluated with particular emphasis on predictors of treatment outcome. Mean follow-up was 22.1 months (range, 3-46). Statistical significance was set at P <.05.Overall success rates were 91%, 79%, and 80% for intravesical UNC, subureteral injection, and extravesical UNC, respectively (P >.05). The mean PUD index for patients who underwent endoscopic treatment was significantly lower (P <.05). In the endoscopic group, reflux was detected at the late-filling or voiding phase of voiding cystourethrography (P <.005). In patients, who were diagnosed with video urodynamics, reflux began at higher bladder pressures and volumes in the injection group (P <.005). UNC was more frequently used in patients with the orifice at the neck or dome (P <.005).For injection in the lower PUD index, onset of reflux at late-filling or voiding phase on voiding cystourethrography, higher pressure and volume on video urodynamics, and C position orifice are positive predictive parameters for success. Bilateral reflux with high PUD index and grade 5 VUR are associated with failure of intravesical reimplantation. Presence of grade 5 VUR and an early onset of reflux outstand as negative predictive factors for unilateral extravesical UNC.

  • An unusual cause of infantile gynecomastia: sertoli cell tumor.
  • 2011
  • Ingår i: Journal of pediatric hematology/oncology. - 1536-3678. ; 33:3, s. 238-40
  • Tidskriftsartikel (refereegranskat)abstract
    • Prepubertal testicular masses are relatively rare. Sertoli cell tumors account for 2% of prepubertal testicular tumors and very few have occurred in the first decade of life. Gynecomastia can be seen in approximately 5% of patients with testicular mass. We present an 8-month-old boy admitted with bilateral gynecomastia and unilateral testicular mass.

  • Both dorsal and ventral flaps can be used in previously circumcised hypospadic adults with comparable success rates.
  • 2010
  • Ingår i: International urology and nephrology. - 1573-2584. ; 42:3, s. 689-95
  • Tidskriftsartikel (refereegranskat)abstract
    • To compare dorsal and ventral dartos flap outcomes for tubularized incised-plate urethroplasty (TIPU) in terms of success, complication rates and cosmetic appearance in adult circumcised hypospadic men.Forty-two circumcised adult men underwent primary distal or midpenile hypospadias repair for cosmetic reasons by a single surgeon in a prospective randomized trial. Twenty-two patients were randomly selected for TIPU repair with dorsal (Group1, mean age 22.3 years) dartos flap as second layer. Twenty patients were randomly selected for TIPU repair with ventral dartos flap (Group2, mean age 21.1 years). Satisfaction questionnaires were answered by patients before surgery and at postoperative 6 weeks. The operating surgeon also filled in the form blindly at the same postoperative period. The differences between pre and postoperative satisfaction scores for each group were also evaluated. Preoperatively, all cases were evaluated with uroflowmetry and compared with postoperative results measured at 6th week of surgery. P < 0.05 was considered as significant.Mean follow-up was 24 months (4-28). Complications were encountered in 18 and 20% of the patients in groups 1 and 2, respectively. Complications were urethrocutaneous fistula, meatal stenosis, retrusive/proximal meatus and residual curvature. Success rates were 82 and 80%, respectively. No differences were seen in overall satisfaction between the two groups (P = 0.07).Outcome of hypospadias repair in circumcised adults for cosmetic reasons is similar to uncircumcised hypospadics previously mentioned in the literature. Both dorsal and ventral flaps can be used in previously circumcised hypospadic adults with comparable satisfaction and complication rates and uroflow findings.

  • Circumcision: pros and cons.
  • 2010
  • Ingår i: Indian journal of urology : IJU : journal of the Urological Society of India. - 1998-3824. ; 26:1, s. 12-5
  • Forskningsöversikt (refereegranskat)abstract
    • Circumcision is possibly the most frequently performed elective surgical procedure in men. It can simply be described as the excision of the preputium. There have been several studies about the association between circumcision and urinary tract infections (UTI). Many studies have demonstrated that the frequency of UTI increase in uncircumcised males, especially in the first year of life. This review discusses the embryology of the preputium, epidemiology, indications, complications and benefits of circumcision, as well as operation and anesthesiology techniques. It especially examines the association between UTI and circumcision and the importance of circumcision in congenital urinary system anomalies. In addition, this review examines the associations between circumcision and sexually transmitted diseases, including HIV, and the protective role of circumcision on penile cancer.
