Little information is available regarding the correlation between Prader-Willi syndrome and urolithiasis. We report a patient with Prader-Willi syndrome with a renal uric acid (UA) stone. A 23-year-old male patient was admitted to our department with gross hematuria and left flank pain. The blood and urine examination demonstrated hyperuricemia with the presence of UA crystals in the urine. Excretory urography revealed a radiolucent stone (17 x 27 mm) in the left renal pelvis suggesting a UA stone. The stone was removed successfully using extracorporeal shockwave lithotripsy (ESWL) combined with medication for UA metabolism. The stone was thought to have formed as a result of overeating associated with Prader-Willi syndrome, and accompanying overproduction of purine.

The longitudinal intestinal lengthening, described by Bianchi in 1980, has been shown to be effective in improving intestinal function, absorption and transit time in patients with short-bowel syndrome. We report the long-term results of 18 survivors of a series of 25 intestinal lengthening procedures performed since 1984. Mean age of the patients was 18 months (range of 5 to 52 months), mean follow-up 6 years (0.9 to 12 years). Parenteral nutrition was progressively reduced in all patients and discontinued after 1 to 10 months (mean 5.1 months). Frequently encountered problems during long-term follow-up are hyperphagia, hyponatremia and hypochloremia, metabolic acidosis, including D-lactic acidosis, cholelithiasis and urolithiasis, gastro-esophageal reflux, dystrophy and symptoms caused by secondary dilatation of the lengthened bowel loops: a protruding abdomen, enteral stasis, leading to constipation or diarrhea with bacterial overgrowth. Overall performance has been acceptable in 13 out of 18 patients. Longitudinal intestinal lengthening is effective enabling patients with short-bowel syndrome to be weaned from parenteral nutrition, allowing for long-term survival. However, it is only one step on a long and difficult way. Multiple problems have to be searched for and adequately dealt with to achieve an acceptable and future worth living.

Urolithiasis is a multifactorial recurrent disease of world-wide distribution in rural, urban, industrial and non-industrial regions. Changes in urinary pH is a risk factor especially with hyperuricosuria, hypercalciuria or hyperoxaluria. With recurrence, hypercalcuria and higher urinary oxalate levels are more frequent. Hypercalciuria and hyperuricosuria showed correlation with family history of stones. The ionic relations between various stone forming salts in urine of patients are opposite to that in controls and are well represented in stone composition. Obesity is a risk factor in both genders. Over eating a diet rich in all nutrients was associated with hyperuricosuria while a diet high only in fat was associated with other urinary disturbances. High protein and fat intake are risk factors. High or low calcium diet was associated with urolithiasis and supplemental calcium is not a risk factor. Potassium and magnesium citrate are potent in inhibiting the growth of stone fragments after extracorporeal shock wave lithotripsy. Whether in patients or normal subjects, drinking hard water should be avoided; tap water or low calcium content water is preferable. Seasonal variations in temperature affected urinary volume, pH and relative saturation of uric acid. To prevent recurrence, patients should maintain high fluid intake achieving a urine volume of 2 liters per day.
