Histomorphologic features of ultrasonic renal injury.

Fifteen-second exposure of rabbit kidneys to 2 MHz focused ultrasound with approximately 900 w/sq cm acoustic power consistently produced localized parenchymal destruction. Evolution of the lesions was followed histologically over a one-year period. The lesions were sharply delineated from outlying renal tissue and had a concentric multizonal structure. Resorption of the damaged tissue with scarring was completed in 6 to 12 months following intermediate phases characterized by cellular infiltration. The lesions are compared to other models of renal injury, particularly with respect to cellular infiltration. A combination of mechanical, thermal, and ischemic factors seem to be responsible for development of ultrasonic lesions. The sharply circumscribed nature and ultimate complete scarring of the lesions suggest the feasibility of ultrasound in achieving selective complete destruction of renal parenchyma.

Transpubic repair of vesicourethrovaginal fistula.

A patient with recurrent urinary vaginal fistula involving bladder, bladder neck, and urethra was treated by transpubic approach. This afforded excellent exposure for careful repair of the urologic defects. Difficulty with ambulation during the first few weeks postoperatively may be related to removal of larger segment of pubic bone than is usually reported.

Response of rat testis to localized induced hyperthermia.

A method is presented in which the rat testis is extensively mobilized through a low abdominal incision, but in which its blood supply is carefully preserved. Localized hyperthermia is induced in this mobilized testis by water bath immersion. The tissue temperature is measured during and after immersion by means of a thermocouple inserted into the tissue. The relative sensitivity of spermatogenic tissue to increased temperature is confirmed and the relative resistance of Sertoli and Leydig cells is noted. Minimal or absent inflammatory reaction to thermal destruction of testicular cells is found as long as the tubule is intact. A marked peritesticular inflammatory response is noted when the total testicular tissue is destroyed at the highest temperature tested.

Wallace method of ureteroileal anastomosis.

The Wallace technique for ureteroileal anastomosis was used in 28 consecutive patients requiring urinary diversion. Details of the surgical technique are reported. The method is found to be appropriate for children and adults, for primary ureteroileal anastomosis, or for revision of previous ureteroileal anastomosis done by other techniques, and for patients with one or two ureters. Its continued use appears to be indicated.

Recent advances in the diagnosis and management of blunt renal trauma.

Experience with 207 cases of blunt renal trauma is reviewed. We have found that renal scans and selective renal arteriography are the most informative diagnostic tests. However, in a small community setting we suggest use of an infusion urogram and a retrograde pyelogram. Our accuracy rates with these 4 diagnostic tests are listed and selected cases are illustrated. We believe that if exploration is warranted, kidney salvage rates will be improved because of an accurate assessment of the extent of renal injury.

Cadaver donor nephrectomy.

Optimal preservation of renal and ureteral structure and function is attempted by maintenance of renal circulation during heart-beating cadaver nephrectomy. Modifications of Ackermann's en bloc procedure for removal of cadaver kidneys are suggested to adapt this procedure to the heart-beating cadaver situation.
