Primary congenital bladder diverticula in boys.

Three male patients ranging in age at diagnosis from eight to seventeen years were found to have presumed primary congenital bladder diverticula. All 3 patients had a solitary documented urinary tract infection (Staphylococcus 2, Escherichia coli 1), 1 patient presented with gross hematuria, and in 1 patient the diverticulum was an incidental finding. In all cases, there was no radiologic evidence on voiding cystourethrography of physiologic or anatomic ureteral or bladder outlet obstruction. In a nine-year-old boy there was ipsilateral renal agenesis, an intra-abdominal undescended testis, and an atretic ureter arising from the diverticulum. The older boy had Ehlers-Danlos syndrome. If the diverticulum is enlarging, compromises the ureterovesical valve mechanism, or by virtue of incomplete bladder emptying is believed to promote urinary tract infection, it should be removed. A surgically conservative course is followed in the Ehlers-Danlos syndrome because of the bleeding tendency and tissue abnormalities.

Ultrasonographic diagnosis of fetal hydronephrosis in utero.

Ultrasonography offers a noninvasive method to visualize antenatal or neonatal anatomy which will lead to early detection and treatment of abnormalities. In these 2 cases, ultrasound allowed prompt diagnosis of hydronephrosis despite normal physical examination and laboratory values at birth.

Principles of management of the persistent cloaca in the female newborn.

The persistent cloaca in the female newborn is one of the most complex and challenging developmental malformations that the pediatric urologist will encounter. A review of 5 patients seen at this center and 34 completely documented cases was undertaken to characterize the defects and devise a logical diagnostic and therapeutic approach. Diagnostic steps include the search for associated anomalies, which were present in the upper urinary tract (33 per cent), gastrointestinal tract (13 per cent), cardiovascular system (13 per cent), central nervous system (10 per cent) and respiratory tract (5 per cent). Delineation of the cloaca and its anatomic relationships is determined by abdominal x-rays, injection of contrast material into the cloacal channel, excretory urography and endoscopy with selective catheterization. Surgical treatment begins with a diverting right transverse colostomy in the newborn period followed by rectal pull-through when the patient weighs 25 pounds. Vaginal pull-through should be performed at the same time as the rectal pull-through if the vagina enters the cloaca high. If the cloacovaginal communication is low a vaginoplasty by a posterior flap procedure can be done when the child is 10 to 12 years old. Even is anatomy is reconstructed in an ideal manner urinary and fecal continence cannot be assured since congenital neurologic dysfunction is not uncommon.

The ureteral stump after nephroureterectomy.

Herein we review 70 cases of transitional cell carcinoma of the upper urinary tract. When complete nephroureterectomy was not performed transitional cell carcinoma developed in 30 per cent of the remaining ureteral stumps. Single incision nephroureterectomy did not include the intramural ureter in 50 per cent of the cases in which it was performed. When nephroureterectomy is selected as treatment for carcinoma of the renal pelvis or ureter a cuff of bladder, which includes the ureteral orifice, should be removed. A second incision may be required for adequate exposure.
