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.

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.

Reanastomosis of completely transected penis in canine: Review of current concepts

The multiple problems associated with the amputated penis are challenging and often difficult. Our experience with reanastomosis of a completely transected canine penis and a brief review of current concepts of the literature are described.

Ureteral Trauma: Effects of Ureteral Ligation with and without Deligation-experimental Studies and Case Reports

Inadvertent ureteral ligation is a well recognized risk during abdominal, retroperitoneal and pelvic operations. The feasibility and the safety of ureteral ligation treated with deligation have been documented. Herein is presented an over-all evaluation of the experience with ureteral ligation treated by deligation in 32 dogs and 4 women.

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.

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.

Reconstruction of bladder neck and prostatic urethra: Clinical experience with bladder flap

Abstract The authors have utilized the bladder-flap procedure in 16 patients from 1967 to 1972. The technique is detailed, and complications and long-term follow-up results are given.

Sutureless bivalve nephrotomy with compression hemostasis

Experimental hemostasis in sutureless bivalve nephrotomy was used on 25 consecutive dogs. The result of this study and the review of the literature are described.
