Unusual cause of acute urinary retention in a child.

A five-year-old child presented with a history of acute urinary retention for eighteen hours. Extensive diagnostic evaluation proved the presence of a retrovesical pelvic mass, which on surgical exploration was found to be an acutely inflamed appendix.

Traumatic rupture of horseshoe kidney with partial ureteral duplication associated with supernumerary kidney.

The first reported case of traumatic rupture of a horseshoe kidney with partial ureteral duplication and an associated supernumerary kidney is presented. A review of the incidence, hypothesis of embryogenesis, associated anomalous development, and acute surgical management of this unique renal anomaly is provided.

Hypertension as complication of vesicoureteral reflux in children.

Eight cases are reported of female children presenting with hypertension and found to have primary vesicoureteral reflux with chronic pyelonephritis. In 6 patients renal function was essentially normal while 2 had azotemia and progessive renal deterioration. As a result of early surgical intervention in the form of antireflux procedures, occasionally combined with unilateral nephrectomy for renin-dependent lesions, 5 of the 8 had complete disappearance or amelioration of hypertension with stabilization of renal function. The interactions of each member of the triad--vesicoureteral reflux, pyelonephritis, and hypertension--are reviewed with emphasis on pertinent pathophysiologic concepts regarding their roles in the production of progressive renal deterioration.

Hypernephroma in children.

Two cases of childhood hypernephroma are presented, bringing to 88 the number of cases of this unusual tumor authenticated in the literature. Both children were black males, four and eight years old. Both had Stage II right renal lesions which were treated with radical nephrectomy and postoperative irradiation. One has been followed up for over seven years and is free of disease. A brief summary of the incidence, treatment, and prognosis of this unusual childhood malignancy is presented.

Experience with the Horton-Devine dermal graft in the treatment of Peyronie's disease.

We treated 15 patients with Peyronie's disease surgically with the dermal graft technique described by Horton and Devine. Details of the preoperative management and surgical technique are provided. Return of normal sexual function without residual chordee or pain was achieved in more than 75 per cent of the patients, suggesting that this is the procedure of choice in the management of severe Peyronie's disease.

Gunshot wounds of the ureter: a 15-year review of 63 consecutive cases.

We reviewed 63 consecutive cases of gunshot wounds of the ureter seen during a 15-year period. The importance of prompt recognition and aggressive surgical management is emphasized, with particular attention being placed on adequate debridement and spatulated splinted watertight ureteroureterostomy. Our philosophy of management for individual injuries is discussed along with our complications and results. This series is the largest reported to date of ureteral gunshot wounds.
