[Peritonitis after spontaneous rupture of a pyonephrosis into the peritoneal cavity. Apropos of a case].

Peritonitis by fistulization of a pyonephrosis is an extremely rare complication usually diagnosed perioperatively. Treatment is by immediate or deferred nephrectomy after ensuring the functional condition of the contralateral kidney.

Fluoroscopically guided percutaneous transrenal electroincision of ureterointestinal anastomotic strictures.

A new technique for electroincision of a strictured ureterointestinal anastomosis is described that uses a sphincterotome and high frequency current. After placement of a percutaneous nephrostomy tube a 7F "wire guided" sphincterotome was placed into the stenosis. The cutting wire was then deflected while cutting current was applied intermittently.

Laser treatment of obstruction from incrusted ureteral catheter.

Incrustations may develop on ureteral catheters and cause obstruction. We report a case in which obstruction was relieved by laser lithotripsy inside the lumen of the catheter. This completely noninvasive technique may prove to be useful in selected cases.

[Use of papillotome for antegrade treatment of ureteral stenoses and uretero-ileal anastomotic strictures under radioscopic control. Experimental study in dogs and clinical application].

A new technique of electro-incision of ureteral stenoses and strictured uretero-enteric anastomoses is presented. Incision is performed with a papillotome, routinely used to achieve endoscopic retrograde sphincterotomy of the duodenal papilla. Group I: 7 ureteral stenoses were performed, on a dog model after surgical ligation of the lumbar ureter.
