Figure 1 Abdominal CT scans of a patient with ureterosigmoidostomy and obstructive uropathy, showing (A) marked dilatation of the right renal pelvis (white arrow) and (B) a large amount of urine filling a wide and tortuous sigmoid colon along with part of the descending colon.
To further investigate the patient's ureterosigmoidostomy, antegrade pyeloureterography was performed, disclosing a nondilated collecting system, a slightly tortuous ureter, and an intact ureterointestinal junction allowing rapid passage of the contrast medium into the bowel (Figure 2A,B).
At this point, the patient and his family were advised that rediversion of the ureterosigmoidostomy to a noncontinent conduit was necessary because of a high likelihood of renal deterioration, recurrent urinary tract infections, metabolic abnormalities, and the potential risk of intestinal malignancy.

 Surgical Techniques for the Correction of Bladder Exstrophy
Before surgical treatments were introduced in 1850, patients with bladder exstrophy had to cope with the life-long problems of chronic urinary incontinence, sexual inadequacy, increased risk of adenocarcinoma of the bladder and renal deterioration.
From 1935 until the late 1960s, simple cystectomy, ureterosigmoidostomy and genital reconstruction were the main treatments used.
The popularity of ureterosigmoidostomy, however, declined in the 1960s when its associated complications, including metabolic derangements, chronic pyelonephritis, and urocolonic tumors, became known.

 Cancer Control Journal:Bladder Replacement and Urinary Diversion After Radical Cystectomy
The quest for an ideal technique for urinary tract reconstruction following cystectomy dates back to 1852 when Simon[15] first reported diversion of urine to a segment of bowel by creating fistulas between the ureters and the rectum in a patient with bladder exstrophy.
Initially, efforts were aimed at either bringing the ureters to the skin or diverting the urine to the sigmoid colon to benefit from continence provided by the anal sphincter.[16,17] Prior to the 1950s, the use of the anal sphincter for continence established ureterosigmoidostomy as the urinary diversion of choice.
During this era, techniques of nonrefluxing ureteral anastomoses were improved.[18-22] However, the risk of long-term complications with ureterosigmoidostomy was significant (hydronephrosis: 32%; pyelonephritis: 57%; metabolic derangements: 47%).[23] In 1950, Bricker[2] popularized the use of the ileum as a urinary conduit, which constituted the gold standard for patients who underwent urinary diversion until the 1980s.

However, the program notices that some of the diseases in the second set (e.g., renal failure) may have the exact opposite effect of causing edema.
To confirm this hypothesis it selects the set of leading causes for the first hypothesis, namely, salmonellosis, ureterosigmoidostomy and villous-adenoma.
