To evaluate the safety and efficacy of endoscopically guided percutaneous suprapubic artery forceps litholapaxy for pediatric vesical and posterior urethral stone1 cm in diameter.A retrospective series study of 73 children (68 boys and 5 girls) with vesical and urethral stones less than 1 cm in diameter with an average age of 3.5 years (range 1-9 years) were included in this study. Cases with previous suprapubic surgery, stones of more than 1 cm in diameter, multiple bladder or urethral stone, anterior urethral stones and cases with neurological or anatomical abnormalities were excluded from our study. The bladder was filled and punctured suprapubically by an artery forceps under the vision of the pediatric cystoscopy then the stone is completely crushed. All intraoperative and postoperative complications were recorded. The stone-free rate status was evaluated 2 weeks postoperatively using plain X-ray/ultrasonography.All cases were successful, and the stones were completely crushed to smaller insignificant fragments in a single session. No intraoperative bladder perforation or bleeding was recorded. The mean operative time was 12.5 min (ranging from 9 to 17 min). There were no postoperative complications apart from 2 cases of persistent suprapubic leakage postoperatively for 24 h and the leakage stopped after 48 h with the insertion of 8 Fr Foley catheter. In all cases, no significant stone fragments were found 2 weeks postoperatively.Our technique for management of pediatric vesical and posterior urethral stone less than 1 cm is an easy and safe with no intraoperative or postoperative significant complications.

Objective We report on the feasibility and outcomes of the N-shaped pouch with an afferent tubular isoperistaltic segment as a new technique for creating a capacious, low pressure bladder substitute following radical cystectomy. Methods Between April 2000 and April 2006, 42 patients (36 male, 6 female) with invasive bladder cancer were considered good candidates for orthotopic urinary diversion. All had radical cystectomy with bilateral pelvic lymphadenectomy and orthotopic bladder substitution by an ileal low pressure reservoir (N-shaped) with an afferent isoperistaltic tubular segment. Of the 42 patients, 36 (86%) had squamous cell carcinoma; 6 had transitional cell carcinoma. None of the patients had positive lymph nodes after pathologic examination of the specimen. The patients were available for a median follow-up period of 24.8 months. Follow-up included clinical and radiographic studies to determine functional and oncological outcomes. Results Eleven patients (26.2%) had early complications during the period ≤ 3 months following surgery. Seven of these patients had complications such as wound infection, prolonged ileus, persistent urinary leakage, and deep venous thrombosis that were treated conservatively. One female patient developed a pouch-vaginal fistula that required repair. The remaining 3 patients had oncologic failures, 1 of which was isolated urethral recurrence. Late complications occurred in 15 patients (35.7%). These included pouch stones, outflow obstruction, mucus retention, and adhesive bowel obstruction. Daytime and night-time continence was achieved in 92% and 80% of the patients, respectively, and ureteroileal stricture was observed in 5%. The upper tracts remained unchanged or improved in nearly 95% of the patients. Conclusions Ileal orthotopic bladder substitution (N-shaped) with an afferent ileal tubular segment offers good functional results with good preservation of the renal units. It is considered a safe and technically feasible surgical procedure.
