Seminal megavesicle in autosomal dominant polycystic kidney disease.

abstract
Retrospective analysis of 99 male autosomal dominant polycystic kidney disease (ADPKD) patients compared to an age-matched control population showed seminal vesicle ectasia >10 mm (megavesicle) in 23% (23/99) of ADPKD patients that was not present in any controls (P<.0001). Median (range) seminal vesicle convoluted tubule diameter in ADPKD patients was 4.2 (1.7-30) mm compared to 3.1 (1.7-6.8) mm in controls (P<.0001). Discrete cysts were identified in four ADPKD patients but in none of the control population (P=.12). Seminal megavesicles may explain the infertility sometimes observed in male ADPKD patients.
