PURPOSE: We evaluated functional outcome following heminephrectomy in duplex kidneys.
MATERIALS AND METHODS: A total of 101 patients were identified who underwent upper or lower pole heminephrectomy between January 1995 and December 2000. We retrospectively reviewed 60 case notes with complete data. A total of 37 cases (62%) were diagnosed prenatally, while 20 (33%) presented as single or recurrent urinary tract infection and 3 (5%) as urinary incontinence. Of the patients 52 (87%) had unilateral duplex and 8 (13%) had bilateral duplex kidneys. In addition, 20 of the 60 patients (33%) had ureterocele. Mean age at surgery was 46 months (range 3 to 10 years).
RESULTS: Mean function as assessed by nuclear renography of the duplex kidney before heminephrectomy was 39.9% (range 22% to 61%) and following heminephrectomy was 33.1% (13% to 60%). Mean decrease in function was 6.8%, with a decrease in function of less than 5% in 18 patients, 5% to 10% in 13 and more than 10% in 5. The functional values were increased by 1% to 5% in 9 patients and unchanged in 15 patients after heminephrectomy.
CONCLUSIONS: Following heminephrectomy there was a significant decrease in 8% of patients and a small decrease in function in the remaining moiety in 51%.
