We describe a surgical technique using an anterior bladder wall flap that is sutured to the posterior wall in an onlay fashion creating a flap valve mechanism. Experimental work in dogs demonstrated a significant increase in the leak point pressure in the surgical group when compared to controls (p = 0.019). Voiding cystourethrography and bladder inspection demonstrated an anterior flap valve with no fistula formation in all animals. Histological examination showed a viable anterior bladder wall flap in all cases. This technique was then applied to 6 patients with neurogenic bladder and low urethral resistance that failed to resolve with medical treatment. Urinary continence was achieved in 4 patients. In 1 patient a vesicourethral fistula developed 3 months postoperatively, since the mother failed to catheterize for 12 hours. This techniqu...

Average followup is 25.6 months. Of the patients 9 with neurogenic bladder underwent the original procedure using a midline anterior bladder wall flap. In the 4 ...

In pediatric patients, in the younger ones, in particular, discontinuation of peritoneal dialysis can be problematic--there are difficulties associated with vascular access and hemodialysis. Over a 5-year period 9 children (4 infants, 2 preschool, 3 school-age) required 15 peritoneal access device replacements, without interruption of continuous ambulatory peritoneal dialysis (CAPD). The reasons for catheter replacement were tunnel complications (10), relapsing bacterial peritonitis (3), and fungal peritonitis (2). All catheter removals and placements were performed by surgical method under general anesthesia in a one-step procedure. The new catheters were implanted on the opposite side of the abdominal wall in all except one child, who had a colostomy. All patients received prophylactic antibiotics in th...

To date, however, few limited studies exist to indicate whether clipping and division of the spermatic vessels alone may cause histological abnormalities in the intra-abdominal testis. We evaluated histology and volume of 44 intra-abdominal testes in 35 patients between 4 months and 14 years old at stages 1 and 2 of the Fowler-Stephens procedure. There was a significant reduction in the number of spermatogonia and seminiferous tubules 6 months after ligation and division of the spermatic vessels. No differences were found in the number of Sertoli cells or testicular volume before and after clipping and division of the spermatic vessels. Ligation of the spermatic vessels during stage 1 orchiopexy for intra-abdominal testicles is associated with a significant reduction of spermatogonia. However, no significant changes were observed in the volumetric characteristics of the testicles. Further studies are necessary to evaluate the repercussions of these changes in future fertility.
