A 45-year-old man with stage 5 CKD secondary to hepatorenal polycystic kidney disease with a history of arterial hypertension and hyperuricaemia. Given the progressive deterioration of renal function with the need for renal replacement therapy, and after explanation of the different techniques, a 1 cuff non-self-positioning straight peritoneal catheter was inserted. One month later, after starting CAPD at home with 4 exchanges of 2 litres of 1.36% glucose, the patient came to the Peritoneal Dialysis Unit, reporting inguino-scrotal oedema of 48 hours' evolution. After ruling out orchiepididymitis, CT-peritoneography was performed, as in the previous case, confirming the passage of contrast to the testicles through a permeable vaginal process. Peritoneal rest and transfer to haemodialysis was decided. One month later, the peritoneovaginal duct was surgically closed, and CAPD was restarted in June 2009 without incident or recurrence of the leak.
