Endoscopic management of the obliterated ureteroileal anastomosis.

Endoscopic restoration of a totally obstructed ureteroileal anastomosis was accomplished in 3 patients. The combined use of rigid endoscopy of the ileal conduit and flexible nephroureteroscopy provided full visualization of the blind-ending segments and allowed location of the shortest segment between the lumina. A guide wire was passed through intervening tissue with fluoroscopic monitoring to re-establish internal drainage. This technique offers an alternative to laparotomy and reimplantation in selected cases of ureteroileal stricture.

Electrohydraulic ureterolithotripsy. An experimental study.

Electrohydraulic lithotripsy was performed on ureteral calculi of various sizes and composition in 10 female mongrel dogs. Stones were successfully disintegrated in eight dogs with an overall 80 per cent success rate. Short- and long-term effects of the procedure on the ureter and the kidney are discussed.

Urethral injury: experimental study.

The present experiment was designed to study several challenging therapeutic questions that remain disputable or unanswered: (1) Whether urethral healing post-trauma is influenced by the use of an indwelling urethral stent as an adjunct to suprapubic diversion; (2) the incidence of urethral stricture formation after immediate or delayed urethral repair; (3) the incidence of urethral stricutre formation after partial or complete urethral disruption; and (4) further assessment of radiographic findings in urethral injury. Herein is described the final conclusions we found to be relevant to this experiment.

Electrohydraulic cystolithotripsy.

The protocol and technique of electrohydraulic cystolithotripsy with the SD-1 for the crushing of the bladder calculi is outlined. In our opinion, the instrument is safe and an effective adjunct to the urologist. Urate, phosphate, and carbonate calculi are easy to crush. Oxalate and uric acid stones are more resistant to fragmentation. The procedure is superior to the conventional methods with blind or optical lithotriptors. The method is easy to learn, and application of this technique may be combined in the same session with other urologic procedures; this procedure opens up a new avenue in the treatment of urinary calculous disease.

Radiographic findings immediately after urethral rupture: an experimental study and case reports.

Herein are reported the results of radiographic studies made immediately after experimentally produced partial and complete urethral ruptures. In cases of partial rupture retrograde urethrography demonstrated extravasation of dye at the site of injury and contrast medium in the bladder. In cases of complete rupture retrograde urethrography demonstrated extravasation of dye at the site of the urethral disruption but no contrast medium reached the bladder because of retraction of the divided ends. Two case reports confirmed these findings.

Electrohydraulic lithotripsy: experimental study and case reports with the stone disintegrator.

Electrohydraulic lithotripsy with the SD-1 for crushing bladder stones was performed experimentally, in vitro and in vivo. The results of this experiment in laboratory animals and in 19 patients revealed that the procedure is safe and superior to the conventional methods with blind or optical lithotriptors. The methods is easy to learn and application of the technique may be combined in the same session with other urological operations. This procedure was done more than 50 times in toto without any complication.
