Segmental calculus disease: potential of parital nephrectomy.
Partial nephrectomy was performed on 71 renal units between 1962 and 1978 for segmental calculus disease. Parenchymal scarring associated with an infundibulocalyceal stone, which was usually branched, was the indication for resection. Stone analysis demonstrated an equal incidence of idiopathic and struvite stones. Perioperative morbidity was minimal, but pyelocutaneous urinary drainage prolonged the hospitalization of 5 patients. In 2 cases, the cause was an obstructing retained calculus. Retained calculi occurred in 3 other patients, one requiring early nephrectomy for sepsis. Fifty-seven patients were followed for longer than twelve months. Ipsilateral calculi recurred in 12 per cent of kidneys, and contralateral new calculi developed in the same number. Ninety-four per cent of patients with preoperative urinary tract infections had sterile urine at follow-up. From the results of this and other series, partial nephrectomy compares favorably with extended pyelolithotomy and anatrophic nephrotomy for segmental calculus disease associated with parenchymal scarring and/or a deformed collecting system.
