ResumoWe evaluated functional outcome following heminephrectomy in duplex kidneys.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).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.Following heminephrectomy there was a significant decrease in 8% of patients and a small decrease in function in the remaining moiety in 51%.
