[Clinical research on congenital hydronephrosis--significance and indication of the preliminary nephrostomy].
Clinical data of 31 patients (34 renal units) with severe congenital hydronephrosis who had received preliminary nephrostomy were reviewed to survey functional recovery of the kidneys and the significance of preliminary nephrostomy. The results were as follows: 1. In most cases, the renal function based on Ccr and 99mTc-DMSA renal scintigraphy after nephrostomy could not improve beyond preoperative one. 2. A close linear correction was found between the thickness of renal parenchyma before preliminary nephrostomy and the renal function after the nephrostomy. 3. Preliminary nephrostomy is indicated for severe hydronephrosis in neonates and infants, obstruction of the lower ureter, and serious general condition, which need accurate split renal function, and for patients without accurate diagnosis.
