A case of transitional cell papilloma of the ureter is reported in a seven-year-old boy who had a history of left flank pain, involuntary voiding and nocturnal enuresis, and was found to have ureterohydronephrosis of a solitary left kidney and renal insufficiency. Renal function and morphology were restored by cutaneous loop ureterostomy, neoureterocystostomy and ureterostomy closure in a staged repair.

The case of a 5-year-old girl, complaining of left abdominal and flank pain, is reported. The excretory urogram and retrograde pyelography showed an obstruction located at the left upper ureter with hydronephrosis. Exploration revealed a small ureteral polyp obstructing the lumen. The polyp along with the short segment of the ureter was resected. Diagnostic and therapeutic considerations are discussed.

A 44-year-old man presented with a history of sudden onset left flank pain, accompanied by nausea and microhematuria. The diagnosis of ureteropelvic junction calculus was made and the patient was scheduled for extracorporeal shock wave lithotripsy (ESWL). ESWL uses an electrical spark to generate a shock wave that is focused on a stone in the ureter or kidney. The shock waves mechanically stress and crush the stone, eliminating the need for manipulation or open procedure. The pain of ESWL is caused by skin sensation. Eutectic mixture of local anesthetics (EMLA) cream (2.5% lidocaine and 2.5% prilocaine) has been used as a topical anesthetic on intact skin for various minor procedures. Studies have shown that it is effective in dramatically decreasing or eliminating the pain of ESWL. The use of topical EMLA as an anesthetic management technique for a patient undergoing ESWL is described.

Spontaneous ureterocolic fistula is rare and usually caused by urinary calculi. We present the fifth reported case of spontaneous ureterocolic fistula caused by diverticular disease of the colon. Review of these cases revealed a preponderance of women (3:1 ratio), with mean age of 77 years. These patients may have a protracted course before an accurate diagnosis is made (up to 10 years) because of the typical vague presentation. Urologic symptoms predominate, especially urinary tract infection (100%), fecaluria (75%), and abdominal (75%) or flank pain (50%). Barium enema is the most reliable diagnostic test in demonstrating the fistula (75%) compared with intravenous pyelogram (33%) or retrograde pyelogram (25%). The left ureter is usually involved (75%). Surgical intervention is generally directed towards resection of the diseased bowel with primary anastomosis when feasible. Surgical manipulation of the urinary system is unnecessary except for removing a non-functioning, infected kidney. Results of surgery were excellent, with 100 per cent cure and one unrelated mortality on long term follow-up. We recognize the potential for increase in this type of internal fistula, given the increasing lifespan and the established increase in incidence of colonic diverticular disease with advancing age. The correct diagnosis can often be determined preoperatively (75%), and surgical intervention is routinely successful.

A 12-year-old boy presented with fever and flank pain bilaterally. Intravenous pyelogram revealed multiple stones and hydronephrosis in the right kidney and an obstructive filling defect at the left upper ureter. Exploration of the left ureter revealed a fibroepithelial polyp. The presented case was an example of the unreported association between fibroepithelial polyp and contralateral nephrolithiasis.

Laparoscopic transposition and reanastomosis of a circumcaval ureter were performed in a 52-year-old man with right flank pain. A preoperative perfusion pressure study revealed abnormally high intrapelvic pressure. Under laparoscopy, the renal pelvis was divided above the ureteropelvic junction and the ureter was relocated from behind the vena cava. A 5 cm segment of redundant ureter containing the postcaval segment was resected and the ureteral end and renal pelvis were reapproximated with interrupted sutures by intracorporeal knot typing. The postoperative convalescence was uneventful, not necessitating the administration of analgesics. The patient resumed full activities 3 weeks later. The intravenous urogram and renogram obtained 2 months after the operation revealed remarkable improvement in the ureteral obstruction.

Inverted growth of transitional cell carcinoma in the ureter is reported. A 71-year-old female visited us for right flank pain and gross hematuria. Hematuria from the right ureteral orifice was found by cystoscopy. Intravenous pyelography revealed right hydronephrosis and a filling defect in the right ureter, but the filling defect moved to the lower ureter. Computerized tomographic (CT) scan demonstrated a tiny lesion in the right ureter. Under a tentative diagnosis of right ureteral tumor, flexible fiberoptic ureteroscopy was performed. As a pedunculated tumor with a smooth surface was found, biopsy was performed. Since pathological examination showed malignancy, right nephroureterectomy was performed. Histological diagnosis was transitional cell carcinoma, grade 1. Cancer was covered by normal transitional epithelium, and developed inverted growth. This is a rare case of inverted growth of the transitional cell carcinoma in the ureter.

Injuries to the ureter from blunt trauma occur most often at the ureteropelvic junction. A delayed diagnosis is typical because of the presence of other injuries. Injuries occurring to other parts of the ureter are usually over the transverse processes. The case of a 15-year-old boy with a mid-ureteral contusion from blunt trauma is presented, in whom compression or impaction of the ureter across the L5 vertebra caused edema late and therefore a partial obstruction. Such injuries should be considered when there is delayed abdominal or flank pain, especially in children.

From March 1988, 19 vesicoureteral reflux (VUR) patients were treated by endoscopic injection of Teflon paste. Of these patients 17 cases 27 ureters were followed for more than one year. After injection of Teflon paste, reflux was eliminated in 63%, decreased in 30%, and unchanged in 7%. Then 7 ureters were injected twice and 1 ureter three times. Finally, reflux was eliminated in 93% of all cases, and decreased in 7%. Early complications were fever up in 4 cases, flank pain 3, acute cystitis 1. In the follow up period, acute cystitis occurred in 1 patient, ureter stone in 1, and renal failure in 1. However, the ureter stone and renal failure were probably not caused by this procedure.

A 63-year-old man was admitted with right flank pain, nausea and chill. CT scan revealed right hydronephrosis and rupture of ureter, but tumor or stone was not detected in the CT scan. However retrogradepylelography revealed right lower ureteral tumor, and this patient was treated by right nephroureterectomy and partial cystectomy. Histopathological examination of ureteral tumor showed transitional cell carcinoma. Spontaneous rupture of ureter due to ureteral cancer is a rare case, which has not been reported in the Japanese literature. Clinical study was performed about cases of spontaneous rupture of ureter which have been previously reported.
