Simultaneous bilateral pyeloplasties.

A technique is described which gives excellent results in the treatment of unilateral hydronephorsis and allows for simultaneous bilateral pyeloplasties. The advantages for the patients with bilateral hydronephrosis are a single admission to hospital and a single anaesthetic and operative procedure. The exposure is superior to that achieved by a loin incision, allowing the surgeon to perform the pyeloplasties more rapidly and with less traction on the renal vessels. Over a follow-up period of 1-7 years no subsequent pyeloplasty or nephrectomy has been required and all 11 patients are well and symptom free.
