Analysis of 10 case histories shows that the picture of the acute abdomen may predominate in acutely exacerbated pyelonephritis. Viscero-dermal reflexes with hyperalgesia and muscular defense, visero-visceral organ reflexes with shock, vomiting, meteorism and disturbances of intestinal motility and metabolic acidosis are temptations to laparotomy. Fever in particular, pathological urinalysis, renal acidosis and occasionally hyperchloremia suggest the diagnosis of "abdominal type of acutely exacerbated pyelonephritis".

Although various complications such as electrolyte imbalance and urinary infection are known to be induced by ureterosigmoidostomy, it is still a surgical technique difficult to ignore since it allows patients to lead an almost normal life without the encumbrance of external urinary devices. At our hospital, we performed eighteen ureterosigmoidostomy operations between 1976 and 1985. Herein, we review the postoperative conditions of electrolyte, renal function and other complications. The patients (16 male, 2 female) were between 53 and 72 years old, the mean age being 61.5 years. The primary diseases were bladder tumor (14 patients), prostatic cancer (2), carcinoma of the female urethral diverticulum (1) and urethral stricture (1). As to the electrolytes, both serum Na and serum K values fluctuated within the normal range. Hyperchloremia was detected in 4 cases (22.2%), but it was only slightly above the normal range and the conditions were more or less stabilized a year after the operation. Although blood urea nitrogen had a tendency to elevate one or two years after the operation, serum creatinine fluctuated within the normal range. During the observation period, only 7 of the 18 cases (38.9%) showed complications, the major complication being pyelonephritis (3 cases). Postoperative excretory urogram revealed slight to medium hydronephrosis two months after the operation in 9 of the 18 cases (50%), but most of these conditions were normalized within a year. Four patients died after leaving hospital; 3 due to the recurrence of cancer and one due to pneumonia. The 14 other outpatients are enjoying a normal life without the use of any external urinary device.

Urinary undiversion is an accepted technique in a highly selective patient population. We reconstructed the urinary tract in six female mongrel dogs. A 15 cm. segment of ileum was isolated, both ends were closed and bowel continuity re-established. The proximal two-thirds of each ureter were anastomosed to the proximal end of the ileal segment. The distal one-third right ureteral segment, in continuity with the bladder, was anastomosed end-to-side to the distal ileal segment. Information from the intravenous pyelograms, renal function tests, electrolytes and pathological studies showed normal upper tracts without dilatation or obstruction, preservation of renal function and normal electrolytes except for mild hyperchloremia in all 6 animals. There was chronic pyelonephritis in one animal and mild focal renal inflammation in two animals. The uretero-ileal anastomoses were patent and the ureters were not dilated. The interposed ileum functions well as a conduit and does not become a reservoir over time. We believe incorporating ileum into the urinary tract in this technique of undiversion is a safe and effective clinical alternative in selected patients.

Clinical studies were made of 60 patients who had undergone ureterosigmoidostomy at our department. The 45 men and 15 women ranged from 35 to 73 years old, with a mean of 59.2 years. Ureterosigmoidanastomosis was performed using the modified Coffey II technique in this series. Bladder tumor was the reason for the operation in 55 cases, uterine cancer in 2, contracted bladder in 1, vesicovaginal fistula in 1 and urethral stricture in 1. In the excretory pyelogram one month after the operation, normal findings and slight hydronephrosis were observed in 37% and 63% of the patients, respectively. However, the pyelogram 6 months after the operation demonstrated normal findings in 61% of the patients, slight hydronephrosis in 34% and moderate hydronephrosis in 5%. None of them showed severe hydronephrosis. Slightly increased BUN level (less than 30 mg/dl) was seen in 15 out of 45 patients (32%) at one year after ureterosigmoidostomy. However, serum creatinine level was not above normal throughout the postoperative course. Although postoperative hyperchloremia was appreciably detected, it was easily managed by the administration of sodium bicarbonate. Serum sodium and potassium levels remained stationary. Of 35 patients observed for more than one year after operation, 11 patients (31%) had developed fever due probably to pyelonephritis, but sigmoidography failed to demonstrate any ureteral reflux. Either urinary or fecal fistula, a complication in the early postoperative period, occurred in 10 patients (17%). One of these patients died. Five patients were cured by conservative treatment. The remaining 4 patients underwent surgical treatment that was ureterocutaneostomy , nephrectomy, or colostomy.(ABSTRACT TRUNCATED AT 250 WORDS)

Although various complications such as electrolyte imbalance and urinary infections are known to be induced, ureterosigmoidostomy may still prove to be useful on selected patients who desire a continent form of internal diversion. At our hospital, we performed nineteen ureterosigmoidostomy operations in the seven years between 1981 and 1987. Herein, we have reviewed the postoperative conditions of electrolytes, renal function and other complications. The patients (17 male, 2 female) were between 43 and 75 years old, the mean being 60.3 years. The primary disease was bladder tumor with histopathological findings of transitional cell carcinoma (17) and squamous cell carcinoma (2). Post-operative fluctuations in electrolyte values of Serum Na and Serum K were within the normal value. Hyperchloremia was initially detected in four cases (21.0%), but these were only slightly above the normal range and a year after the operations the conditions were stabilized. Although blood urea nitrogen had a tendency to elevate one or two years after the operation serum creatinine fluctuated within the normal range. After the operations, we administered 10% sodium potassium citrate solution to all patients to prevent hyperchloremic acidosis. During the observation period, only four out of nineteen cases (21.0%) exhibited pyelonephritis. No other complications were observed. Postoperative excretory urograms revealed slight to medium hydronephrosis two months after the operation in four out of nineteen cases but most of these conditions were normalized within a year. Nine patients died after leaving the hospital; seven due to the recurrence of cancer and two due to pneumonia. The ten remaining patients are enjoying normal lives without the use of any external urinary device.
