The effect of uninephrectomy on progression of renal failure in autosomal dominant polycystic kidney disease

M Zeier, S Geberth, A Gonzalo, D Chauveau, JP Grunfeld and E Ritz
Department of Internal Medicine, University of Heidelberg, Germany.

The evolution of renal failure was compared in 47 patients (21 male, 26 female) with autosomal dominant polycystic kidney disease (ADPKD) in Germany, France, Spain, and Portugal who had undergone uninephrectomy (UNX) (median age at uninephrectomy, 41 yr; range, 22 to 54) and 47 non- UNX matched controls. UNX was usually performed because of uncontrolled urinary tract infection (N = 30), stones (N = 8), trauma (N = 2), or hemorrhage (N = 7). Median serum creatinine at UNX was 2.1 mg/dL (0.9 to 4.3). Twenty-eight of the 47 uninephrectomized patients progressed to end-stage renal failure. When the age at renal death was evaluated by survival analysis, only minor and nonsignificant acceleration was seen in the uninephrectomized patients (median, 50 yr; p25 = 43.6 yr; p75 = 58.3 yr, where p is the percentile) compared with non-UNX patients matched for age, sex, and serum creatinine at the time of UNX in the propositus (51.2 yr; p25 = 48.6 yr; p75 = 56.1 yr). In addition, the median interval for serum creatinine to rise from 4 to 8 mg/dL was similar in UNX (21.3 months) versus nonuninephrectomized ADPKD patients (21.9 months). Renal survival differed in the two genders. In females, no significant difference of age at renal death was found between UNX (median age, 51.6 yr) and non-UNX ADPKD patients (53.7 yr). In male UNX patients, age at renal death was slightly (but not significantly) less than in non-UNX patients (median age, 47.3 versus 52.7 yr). All male patients reaching end-stage renal failure before age 44 were severely hypertensive.
