[Extracorporeal shockwave lithotripsy in patients with the long-term presence of stones in the ureter].

28 patients with long-standing ureteroliths (present in the ureter for 2 months and longer, size 0.8-1.5 cm) were exposed to extracorporeal impulse lithotripsy (EIL). 26 of them were found to have inflammation in the kidneys and upper urinary tracts. Comparative data on EIL effect show that patients with long-standing ureteroliths need more intensive and long EIL treatment, that fragmentation is more troublesome in oxalate monohydrates and phosphate stones with hydroxylapatite. 4 cases eventuated in operative intervention, in 3 cases ureterolith extraction was performed. EIL results in long-standing ureteroliths depend on the presence of renal and urinary tract inflammation, severity of periureteritis, chemical composition, density and structure of the stones.

[The laparoscopic treatment of varicocele].

Laparoscopic treatment of varicocele is described for 37 patients. The operation was performed under endotracheal, epidural and intravenous anesthesia with ligation of the testicular vein in 18 patients. Ligation with the dissection was conducted in 19 patients. On the first postoperative day 2 patients were given promedol (2%, 1.0 ml), the rest were injected baralgin (2-3 injections). The patients were discharged after 1-2 days of hospital stay and resumed their usual way of life 2-7 days after the discharge. One month later varicocele disappeared in 29 patients, diminished in size in 7 patients, pain relief occurred in 15 patients. Due to its advantages (simple performance, good visualization of the testicular vein, minimal use of narcotic drugs, short hospital stay, absence of serious complications) laparoscopic treatment may be considered as a method of choice.

[The prediction of the results of extracorporeal shockwave lithotripsy].

The disease history, objective, x-ray and aggregatometry evidence has been analyzed for 188 nephroureterolithiasis patients to make the prognosis of extracorporeal impulse lithotripsy (EIL). If the concrements presented at x-ray picture as structurally homogeneous, medium-contrast, with even margins, fragmentation occurred after 3-4 sessions in 81% of the cases. Low or high contrast calculi with heterogeneous margins disintegrated after 1-2 EIL sessions. Flat calculi were easier to crush than round ones. A decline or absence of changes on the aggregatometry curves prompted the decision on efficacy of further EIL. The calculi which existed for 6 months maximum were the easiest to crush. The outcome of the previous EIL is also essential for prognosis. Inflammation and obesity worsen EIL results. Variant of EIL regimen and the number of impulses are also prognostically significant.

[The laparoscopic treatment of abdominal cryptorchidism in adults].

Three patients aged 18, 25 and 31 years with abdominal cryptorchidism and concomitant diseases were treated laparoscopically. Macroscopic amd microscopic evidence said in favor of removal of the testis. In one case this removal was done in line with removal of the dysplastic kidney. In another case plastic surgery was conducted of the inguinal hernia on the side of cryptorchidism.
