Of 37 adult patients with ureteroceles, 13 also had calculous disease (35 per cent). Of these 13 cases 7 had single ureters and 6 had duplicated ones. None had a metabolic or urinary abnormality such as hypercalcemia, gout, hypercalciuria or hyperuricuria. Two of the patients were a mother and daugher--the first reported familial incidence of ureterocele with calculous disease. A surgical technique is described for removal of the calculus, excision of the ureterocele and reimplantation of the ureter. The procedure was used in 4 of the 7 patients with single ureters, while the stone passed spontaneously in 2 patients and was treated by ureterolithotomy in 1. A modification of the technique was used in 2 of the 6 patients with duplicated ureters but other surgical procedures were used in the remaining 4. Of 10 stones that were analyzed 2 were struvite and none contained cystine or uric acid. Long-term followup is a requisite to assure control of this clinical entity.

Three adult patients with unilateral renal agenesis/total dysplasia (= aplasia) and with an early chronic renal failure are presented. One patient had renal agenesis without ureter bud and ureteric ostium on one side, and reflux pyelonephritis on the other; one had small compact total renal dysplasia (= aplasia) on one side, while chronic uric acid nephropathy (chronic renal disease as a cause of gout) was diagnosed on the other; the third patient had a total large multicystic dysplasia on one side, and on the other a segmental large multicystic dysplasia. Radiological steps and radiodiagnostic criteria are discussed and the combination of urogenital and extraurogenital anomalies is referred to.

Uric acid urolithiasis develops from various causes. To investigate the clinical and biochemical presentation of patients with uric acid urolithiasis, a retrospective study was designed. A total of 46 cases were enrolled between January 2004 and December 2005. The compositions of the stones were analyzed by infrared spectrophotometry. There were 39 males (84.8%) and seven females (15.2%), with a mean age of 61.5 +/- 10.6 years and mean body mass index (BMI) of 26.7 +/- 3.1 kg/m2. The stone location was kidney in 10 (21.7%), ureter in 22 (41.8%), and bladder in 14 (30.5%). Multiple stones were diagnosed in 36 patients (78.3%). Pre-existing comorbidities included diabetes mellitus in 11 patients (23.9%), hypertension in 23 (50%), gout in 13 (28.2%), and benign prostatic hyperplasia in 14 (30.4%). Mean serum creatinine and uric acid was 1.6 +/- 0.6 mg/dL and 7.6 +/- 1.8 mg/dL, respectively. There were 27 patients (58%) with creatinine > 1.4 mg/dL. The mean urinary pH was 5.42 +/- 0.46. Patients with uric acid urolithiasis were predominantly male, older, with higher BMI, multiple stone presentation, with lower urinary pH, and hyperuricemia. Exacerbation of the renal function should also be of concern because of the high proportion of patients with renal insufficiency diagnosed in this study.
