To conduct a prospective comparison of quality‐of‐life (QoL) outcomes in patients who underwent ileal conduit (IC) urinary diversion with those who underwent orthotopic neobladder (ONB) reconstruction after radical cystectomy for invasive bladder cancers.

Transperitoneal versus retroperitoneal laparoscopic ureterolithotomy: a prospective randomized comparison study.

PURPOSE We compared laparoscopic transperitoneal and retroperitoneal ureterolithotomy approaches, and determined whether one technique is superior to the other. MATERIALS AND METHODS In this prospective randomized study from January 2009 to May 2012, 48 patients with proximal or mid ureteral stones underwent transperitoneal laparoscopic ureterolithotomy or retroperitoneal laparoscopic ureterolithotomy. The randomization occurred on a 1:1 basis. Groups 1 and 2 consisted of patients who underwent transperitoneal laparoscopic ureterolithotomy and retroperitoneal laparoscopic ureterolithotomy, respectively. Demographic and clinical characteristics as well as postoperative data were collected and analyzed. Statistical analysis was performed with SPSS® version 15.0 using the Fisher exact and Mann-Whitney U tests with p <0.05 considered statistically significant. RESULTS The difference in visual pain analog score and mean tramadol requirement on days 1 and 2 between the 2 groups was statistically significant, and was higher in group 1 (p <0.05). Postoperative hospital stay and paralytic ileus rates were significantly higher in group 1 (p <0.05). The differences in total operative time and intracorporeal suturing time between the 2 groups were not statistically significant. However, successful stone removal was equal in the 2 groups. CONCLUSIONS For proximal or mid ureteral large and impacted stones, transperitoneal laparoscopic ureterolithotomy is significantly associated with pain, greater tramadol requirement, ileus and longer hospital stay than retroperitoneal laparoscopic ureterolithotomy. However, successful stone removal remains the same in both groups.

Uroflowmetry nomograms for healthy children 5 to 15 years old.

PURPOSE We determined flow rates and generated flow rate-voided volume nomograms based on healthy children 5 to 15 years old voiding spontaneously in their natural environment. MATERIALS AND METHODS A total of 824 healthy school children of both genders were enrolled. A single uroflow record from each child was evaluated. A total of 103 children with a voided volume of less than 50 ml and/or a staccato/interrupted uroflow pattern were excluded, and 721 records were analyzed. Data were evaluated using several mathematical formulas and goodness of fit was determined. Linear regression analysis was used to generate nomograms. RESULTS Flow rates and voided volumes increased with increasing age, with the effect being more pronounced in girls. No significant difference was noted in uroflow rates from 5 to 10 years, but significant differences (p <0.001) started appearing at 11 to 15 years. Also no significant difference was noted in uroflow rates among children 11 to 15 years. Therefore, 2 age groups were designated, with group 1 consisting of patients 5 to 10 years old and group 2 consisting of patients 11 to 15 years old. There were 222 boys and 122 girls in group 1 and 240 boys and 137 girls in group 2. In group 1 the maximum and average ± SD flow rates were 15.26 ± 4.54 ml per second and 7.68 ± 3.26 ml per second, respectively, for boys and 17.98 ± 6.06 ml per second and 9.19 ± 4.23 ml per second, respectively, for girls. In group 2 these rates were 22.50 ± 7.24 ml per second and 10.78 ± 4.03 ml per second, respectively, for boys and 27.16 ± 9.37 ml per second and 13.48 ± 5.21 ml per second, respectively, for girls. CONCLUSIONS This large study, which expands the scant existing literature on uroflow parameters in healthy children, will hopefully promote wider application of uroflowmetry testing in the pediatric population.

Transperitoneal Transvesical Laparoscopic Repair of Vesicovaginal Fistulae: Experience of a Tertiary Care Centre in Northern India

Objective: To present our experience of treating supratrigonal vesicovaginal fistulae by laparoscopic technique and their long-term follow-up. Material and Methods: Between January 2008 and June 2012, 28 cases of supratrigonal fistulas were repaired by laparoscopic transperitoneal transvesical technique with interposition flap. The obstetric fistula was present in 18 and gynecologic fistula in 10 patients. Single supratrigonal fistula was present in 26 patients and in 2 patients there were 2 fistulae lying side to side. The vaginal opening was closed as single layer interrupted suture and cystotomy closed as single layer continuous suture by 3-0 polygalactin. The omentum was used as interposition flap in all except 2 cases in whom postero-superior vesical fold of peritoneum was used. The open conversion was required in 2 cases. The urethral catheter was removed in 4 weeks following a micturating cystogram. Result: The mean fistula size was 1.2 cm (range 0.8-2.5 cm). Open conversion was performed in 2 cases of whom one had excess carbon-dioxide retention and cardiac arrhythmia and in another case the needle of 3-0 polygalactin was avulsed and lost in peritoneal cavity which was recovered following laparotomy. All patients were continent following the catheter removal. The median follow-up is 24 months. None developed any complication related to laparoscopic repair till last follow-up. Conclusion: Laparoscopic repair of supratrigonal vesicovaginal fistulae is an effective and safe minimally invasive treatment with excellent result.

Percutaneous Nephrolithotomy in Autosomal Dominant Polycystic Kidney Disease: Is it Different from Percutaneous Nephrolithotomy in Normal Kidney?

Objectives: Nephrolithiasis has been reported in 20-28% of patients, of whom 50% are symptomatic for stone disease and 20% require definite urologic intervention. The management of nephrolithiasis includes oral alkali dissolution therapy, extracorporeal shock wave lithotripsy and surgical treatment. In such patients, percutaneous nephrolithotomy (PNL) as a method of stone treatment has been reported in few cases with limited experience. The aim of this study is to present our experience of PNL in autosomal dominant polycystic kidney disease (ADPKD) and assessing the outcome results. Material and Methods: From 2002 to 2011, 22 patients (26 renal units) suffering from ADPKD with stone were managed by PNL. Demographic characteristics, operative parameters and postoperative complications were recorded and analysed. Result: The overall success rate of PNL was 82.1% and PNL with extracorporeal shock wave lithotripsy for clinically significant residual fragments was 92.85% respectively. The hematuria required blood transfusion (n = 9), postoperative fever due to cyst infection (n = 4) and paralytic ileus (n = 3) were recorded. Conclusion: The PNL in ADPKD PNL is safe and effective but have more postoperative complications such as bleeding requiring transfusions, fever due to cyst infection and paralytic ileus.

Leiomyosarcoma, a nonurothelial bladder tumor: a rare entity with therapeutic diversity.

A 22-year-old young woman presented with dysuria and lower urinary tract symptoms that had persisted for 6 months. She was diagnosed with a tumor near the bladder neck. Transurethral resection was done under anaesthesia. The histopathological examination with immunohistochemical staining showed the tumor to be a low-grade leiomyosarcoma. Adjuvant chemoradiation was given, and the patient has been doing well for 12 months of follow-up. Nonurothelial tumors of the bladder are rare and consensus is lacking regarding their definitive treatment. Furthermore, little is known about the natural history and prognosis of this type of bladder sarcoma. We present a minimally invasive treatment for this relatively rare tumor in which bladder preservation was achieved with no evidence of local or distant recurrences during the follow-up to date.

Re: Jens J. Rassweiler, Michael Müller, Markus Fangerau, et al. iPad-assisted percutaneous access to the kidney using marker-based navigation: initial clinical experience. Eur Urol 2012;61:628-31.

We congratulate the authors for this innovative technique in which they demonstrate the feasibility of iPad-assisted augmented reality to achieve accurate access for percutaneous nephrolithotomy (PCNL) [1]. PCNL is considered the gold standard for the management of renal calculus because it is easy to learn, easy to teach, inexpensive, easily available worldwide, and safe and gives good results. We are apprehensive about the introduction of expensive software to obtain access in PCNL for several reasons. This approach would defeat the purpose of PCNL as the gold standard because (1) it would be difficult to introduce the software to most centers around the world, and thus it would be restricted to a few centers; (2) it would translate into a significant increase in expenditure; (3) it would decrease hospital turnover; and (4) it would create less need for acquiring surgical skill. However, it is expected that the expense of computed tomography scan, navigation aids, iPad, WiFi, and control-room establishment would

Urodynamic and continence assessment of orthotropic neobladder reconstruction following radical cystectomy in bladder cancer; a prospective, blinded North Indian tertiary care experience

Aim: The aim of this study is to compare urodynamic and continence parameters among patients undergoing orthotropic neo-bladder substitution with sigmoid or ileal segments. Variations in the Urodynamic parameter between the continent and incontinent patients were also evaluated. Patients and Methods: From January 2008 to March 2012, 44 patients underwent ileal neobladder (IN) reconstruction and 36 patients underwent sigmoid neobladder (SN) reconstruction. Evaluation of Urodynamic and Continence parameters was performed at 12 months after surgery. Results: The average capacity of IN and SN was 510 ml and 532 ml respectively. The voiding pressure, mean peak flow rates and post void residual urine (PVRU) for IN and SN were 27.5 cm H2O versus 37 cm H2O, 15ml/s versus 17ml/s and 36 ml versus 25 ml respectively. Daytime continence for IN and SN was 93% (41/44) and 89% (32/36), and night-time continence was 91% (40/44) and 78% (28/36) respectively. The compliance, maximum cystometric capacity and PVRU in the daytime continent (versus incontinent) were 61 (versus 41), 471 (versus 651) and 22 (versus 124) and in the night-time continent (versus incontinent) were 57 (versus 43), 437 (versus 654) and 18 (versus 105) respectively. Conclusion: A neobladder constructed from detubularized ileum or sigmoid achieves urodynamically proven adequate capacity and compliance with 89-93% daytime and 78-91% night time continence. Continent men when compared with incontinent (both daytime and night time) were more likely to have comparatively higher compliance, lower maximum cystometric capacity and lower PVRU. Urodynamic study could predict which incontinent men would improve with pelvic floor exercises and clean intermittent catheterization (CIC).

Prospective Randomized Comparison Between Transperitoneal Laparoscopic Pyeloplasty and Retroperitoneoscopic Pyeloplasty for Primary Ureteropelvic Junction Obstruction

Background and Objectives: To compare laparoscopic transperitoneal versus retroperitoneoscopic pyeloplasty for primary ureteropelvic junction obstruction in a prospective randomized manner and assess overall results with long-term follow-up. Methods: In this prospective study, from 2008 to 2012, 112 cases of primary ureteropelvic junction obstruction were randomized in a 1:1 ratio into 2 groups. Group I included patients who underwent transperitoneal laparoscopic pyeloplasty, and group II consisted of patients who underwent retroperitoneoscopic laparoscopic pyeloplasty. Demographic and clinical characteristics and postoperative and operative data were collected and analyzed. The statistical analysis was performed with the Fisher exact test, χ2 test, and Mann-Whitney U test for independent groups, and P < .05 was considered statistically significant. Results: The total operative time and intracorporeal suturing time were significantly higher in group II than in group I (P < .001). The visual analog scale score for pain on postoperative day 1 and the requirement for tramadol were significantly higher in group I than in group II (P = .004). The hospital stay and the rate of temporary ileus were significantly greater (P < .036 and P < .02, respectively) in group I than in group II. The success rate of transperitoneal laparoscopic pyeloplasty versus retroperitoneoscopic laparoscopic pyeloplasty was 96.4% versus 96.6% with a mean follow-up period of 30.75 ± 4.85 months versus 30.99 ± 5.59 months (P < .88). Conclusion: Transperitoneal laparoscopic pyeloplasty is associated with significantly greater postoperative pain, a higher tramadol dose, a higher rate of ileus, and a longer hospital stay in comparison with retroperitoneoscopic laparoscopic pyeloplasty. Although the operative time for retroperitoneoscopic laparoscopic pyeloplasty is significantly longer, the success rate remains the same for both procedures.

Tricholithobezoar: An Unusual Late Complication of Neourethral Reconstruction in Aphallia

An 18-year-old man born with aphallia had undergone phallic reconstruction in childhood followed by total urethral reconstruction with a buccal mucosal graft and groin-based pedicle (Singapore) flap urethroplasty at 13 years of age. The patient presented with obstructive voiding symptoms lasting 6 months followed by acute urinary retention. The results of a voiding cystourethrogram showed a filling defect in the distal urethra that had been reconstructed by use of the skin flap. On urethroscopy, a 3 cm×2 cm sized tricholithobezoar was seen in the distal urethra. Pneumatic lithotripsy followed by bulbar urethrolithotomy was performed in the same operation to extract the bezoar. The remaining hairs were mechanically epilated. The patient has been doing well for 6 months of follow-up.
