title: [Ureteroceles].
abstract: Four types of ureteroceles are described: A) ureterocele with single ureter (10%); B) ureterocele with total duplication and intra-vesical development (10%); C) ureterocele with total duplication and extra-vesical development (62%); D) ureterocele with ectopic ureter (3%). Most ureteroceles are now detected by antenatal ultrasonography, allowing early management. The treatment of types A and B is simple depending on the status of the above kidney and ureter: abstention, meatomy, ureterocelectomy with ureteral reimplantation, nephrectomy. In type C, the upper kidney is always destroyed. Two treatments are proposed: upper pole nephrectomy with ureterocelectomy which is a difficult but safe procedure, upper pole nephrectomy with aspiration of the ureterocele which is called the "simplified technique" but requires reoperation in 40% cases. The complicated forms may require either meatotomy for decompression, or diversion by percutaneous nephrostomy. Strangulation of the ureterocele constitutes an emergency.
