Abstract
OBJECTIVE: To describe the urological and nephrological long-term outcome of patients born with classical bladder exstrophy treated with bilateral ureterosigmoidostomies in early childhood. PATIENTS AND METHOD: Out of 42 patients born with bladder exstrophy in Switzerland between 1937 and 1968, 25 participated in this study; seven had died, seven were lost to follow up and three refused consent. Assessment included chart review, clinical examination, and assessment of renal function and morphology. RESULTS: After a follow-up period of 37-69 years ((mean 50 years), 13 of the 25 participants (52%) had their ureterosigmoidostomy still in place. All others had different forms of urinary diversions. Fifteen (60%) patients had normal renal function or mild chronic kidney disease as assessed by estimated glomerular filtration rate. Three patients were on renal replacement therapy. MRI (n=16) showed 10 morphologically normal kidneys. One patient suffered from adenocarcinoma of the colon, five had benign colonic polyps, one urethral papillary carcinoma and 18 no evidence of tumor. CONCLUSION: The majority of our patients have normal or mildly impaired renal function and a well functioning ureterosigmoidostomy. This is remarkable, given the fact that ureterosigmoidostomies are considered to be refluxing high-pressure reservoirs at risk of renal injury and malignancy.
