The use of a kidney removed because of ureteral damage in an unrelated donor has produced a well functioning renal allograft in the transplant recipient. The kidney demonstrated calicectasis and hydronephrosis on an excretory urogram before removal of the ureteral cutaneous fistula. An excretory urogram performed 8 months after the renal allotransplantation of this kidney shows prompt function of a delicate collecting system without any residual calicectasis. This case emphasizes the need for us to explore the possible use of free kidneys removed from living unrelated donors for non-neoplastic diseases of the ureter.

Pyeloplasty for hydronephrosis secondary to ureteropelvic junction obstruction is a proved efficacious procedure. In many cases the clinical improvement effected by technically successful pyeloplasty in children has been reported to exceed substantially radiographic improvement in caliceal appearance. To address this issue in the adult population we did a retrospective review of 52 patients who had undergone pyeloplasty for ureteropelvic junction obstruction. In 91 per cent of the patients the clinical result was satisfactory, while improvement was observed in 92 per cent of the renal units that could have been expected to benefit. The caliceal appearance on the postoperative excretory urogram was normal in only 25 per cent of the cases, showed diminution of calicectasis in 65 per cent, was unchanged in 30 per cent and deteriorated in 5 per cent. Earlier appearance of contrast medium in the upper ureter on the postoperative excretory urogram was seen in all patients who had a satisfactory clinical result. Deterioration of caliceal grade or delayed appearance of contrast medium in the ureter in the postoperative excretory urogram always was associated with a poor clinical result and/or further parenchymal loss. While a salutary effect of a technically successful operation on the clinical manifestations of hydronephrosis secondary to ureteropelvic junction obstruction is not necessarily correlated with improved or normal caliceal appearance it does correlate strongly with improvement of drainage as manifested by earlier appearance of contrast medium in the ureter. Deterioration of the caliceal grade or delayed appearance of contrast medium in the ureter implies that effective drainage is not present, which presages a poor clinical outcome and further loss of renal parenchyma.

The occurrence of ureteral fistulas as a complication of obstetrics is very rare, mostly occurring in developing countries. Only 2 cases of ureterouterine fistulas following dilation and curettage (D & C) have been reported. A 3rd case is reported in this paper. Diagnosis was made by an excretory urogram (IVP). After D & C the patient had hemorrhaged profusely and the IVP showed prominent calicectasis with hydronephrosis in the right kidney. After clinical stabilization, treatment of the pyelonephritis and evaluation of the bleeding disorder, a right percutaneous nephrostomy tube was inserted and vaginal drainage of urine ceased. Later the patient was hospitalized for an elective repair of the ureterouterine fistula. Right ureteroneocystosomy with a psoas hitch was performed to bridge th gap of the ureter to the bladder.

The purpose of this report was to describe a safe, simple, and rapid approach to percutaneous antegrade endopyelotomy. In contrast to standard percutaneous endopyelotomy techniques, in this procedure, the endopyelotomy stent is placed at the outset. The endopyelotomy incision is then made with an acorn-tipped Bugbee electrode directly down onto the stent, in a manner analogous to a ureteral meatotomy in the bladder. The advantage of this approach is twofold. Primary placement of the stent helps to define the appropriate site and direction for the endopyelotomy incision, allowing marsupialization of the proximal ureter into the renal pelvis. Use of this technique also obviates the need to pass a large-caliber stent after the endopyelotomy incision has been made, thereby avoiding a potential risk of ureteropelvic junction disruption. Clinical and radiographic follow-up was available in 29 (76%) of 38 patients who underwent this procedure. Success, defined as a resolution of symptoms and decrease in calicectasis, was achieved in 24 (83%) of the 29 patients. We have found primary placement of an endopyelotomy stent and use of electrocautery as a cutting mode safely facilitates a precise endopyelotomy incision.
