[Extracorporeal lithotripsy of kidney and ureteral calculi after open operations]. / Ekstrakorporalna litotripsiia na bubrechni i ureterni kamuni sled otvoreni operatsii.

Experience is recorded with the application of stroke-wave extracorporeal lithotripsy of calculi which have remained after open-technique operations for coral-shaped calculosis. Fifteen patients, 11 women and 4 men at mean age 43 years have been treated for the period 1.01.1989 through 7.02.1990. They all had nephrostoma placed by operation. Extracorporeal lithotripsy (ECL) was performed mean 14 days after the operation. The mean length of stay in hospital was 23 days. All patients were calculi-free 3 months after ECL. It is recommended to place nephrostoma when the kidney has not been fully freed from calculi during operation, to allow further performance of ECL. This helps to achieve quicker and complete removal of calculi from the urinary tract, which in turn contributes to successful of the urinary infection.

[A new method for the surgical treatment of urinary incontinence following surgery of the prostate]. / Nov metod na operativno lechenie na inkontinentsiiata na urinata sled operatsii na prostatnata zhleza.

A new method is reported for operative treatment of urine incontinence, following transversal adenomectomy and transurethral resection of the prostate gland. The operative technique is described in detail. Its basic point is placing of a small "Ampoxen" ball over the urethral bulbus. Disappearance of the incontinence after such an operation is due both to the compression on the bulbar part of the urethra and to the formation of connective tissue, which proliferates into the sheet being placed. Twelve patients from 62 to 75 years of age were treated in this way. In 10 of them the immediate and the late results are considered very good. Incontinence disappeared until the 3. day after removing the indwelling catheter. In the other two patients the result is considered satisfactory. The encouraging results make the authors prefer the method which they suggest for postoperative urine incontinence.
