A 67-year-old man was referred for further examination of left hydronephrosis. He had undergone anterior resection for rectal cancer 2 years previously and also right lobectomy for a solitary hepatic metastasis one year postoperatively. Antegrade pyelography demonstrated a filling defect in middle portion of the left ureter. Cytology of the aspirated urine was class V. Left nephrourete-rectomy was performed. Histologically metastatic adenocarcinoma with intact ureteral mucosa was demonstrated.

[Imaging studies of excretory urography and computed tomography scan for patients suffering from renal colic]

Renal colic mainly due to urolithiasis is one of the most common morbid conditions in urology and commonly seen in the urology emergency clinic. Imaging studies were performed to evaluate the upper urinary tract of 29 patients suffering from renal colic in the 2 years between November, 1994 and October, 1996. After intramuscular injection of the analgesic (pentazocine, 15 mg), all 29 patients were examined by excretory urography (IVP) at the time of the first visit. In some patients abdominal plain computed tomography (CT) scan was performed consecutively even when extravasation of the contrast medium was not seen. Spontaneous peripelvic extravasation was seen in 14 patients (11 males and 3 females) with urolithiasis; 7 of them were diagnosed by IVP, 5 by IVP plus CT scan and 2 with CT scan only. IVP imaging study followed by plain abdominal CT scan is useful even when the contrast medium is not extravasated on IVP in patients suffering from renal colic.

[A case of multiple organ failure with massive intestinal bleeding caused by methicillin-resistant Staphylococcus aureus in a postcystectomy patient--efficacy of mask continuous positive airway pressure training and intraarterial embolization]

Year 1998

Department of Urology, Fujisawa City Hospital.
A 51-year-old man underwent radical cystectomy with tubeless cutaneous ureterostomy. Methicillin-resistant Staphylococcus aureus (MRSA) enteritis developed postoperatively. MRSA caused critical infections such as pneumonia and sepsis, which subsequently progressed to adult respiratory distress syndrome, massive melena and multiple organ failure. The patient was rescued by intensive management including mask continuous positive airway pressure, systemic vancomycin administration and intraarterial embolization to stop jejunal bleeding.

[Two cases of delayed ureteral fistulas following rectal amputation]

Year 1998

Department of Urology, Osaka Red Cross Hospital.
We report two rare cases of delayed ureteral fistulas which occurred one month following rectal amputation. Case 1 was a 52-year-old male who underwent abdominal perineal resection of the rectum. One month after surgery, the patient had a paralytic ileus. Computed tomographic (CT) scan and drip infusion pyelography showed left ureteral fistula and a large pelvic urinoma. Because retrograde placement of a double-J stent was unsuccessful, antegrade placement of the double-J stent was performed. The fistula and urinoma healed soon after the placement of the double J stent. Case 2 was a 43-year-old male who underwent abdominal sacral resection of the rectum. One month after surgery, a large amount of urine began to drain from the perineal wound. CT scan and retrograde pyelography showed a right ureteral fistula and a large pelvic urinoma. There had been temporary improvement in the discharge without the treatment of the ureteral fistula, only for it to return more profusely. Because placement of a double-J stent was unsuccessful, right percutaneous nephrostomy was performed, after which, a right ureterocysto-neostomy (Boari flap method) was performed. We advocate the initial use of the double-J stent or percutaneous nephrostomy in ureteral fistula. This approach is simple and may cure the fistula. If unsuccessful, it will not hinder subsequent open surgery.
