ABSTRACT
Objective To assess the safety and the curative effect of the combination of minipercutaneous nephrolithotomy (mini-PCNL) and ureteroscopic lithotripsy (URL) in the treatment of nonhydronephrotic staghorn calculi. Methods The clinical data of 53 eases with non-hydronephrotic staghom calculi treated by mini-PCNL combined with URL were retrospectively analyzed. Results Fifty-three cases (64 renal units) were performed first-stsge operation, 9 renal units were stone free in first-stage operation, 33 renal units were stone free in second-stage operation, other 13 renal units were stone free in third-stage operation. A complete stone clearance rate of 85.9%(55/64) was achieved, and after one to three sessions of mini-PCNL and extracorpereal shock wave lithotripsy afterwards that increased to 95.3% (61/64). Blood transfusion was performed in 3 cases, no major complication was noted in the patients. Conclusions The combination of mini-PCNL and URL has more advantages, less invasions, easier recovery and less complications. It provides a new minimally invasive way for non-hydronephrotic staghorn calculi.
ABSTRACT
Objective To explore emergency treatment methods for acute renal failure caused by negative imaging ureterolith. Methods There were 36 cases of acute renal failure caused by negative imaging ureterolith, which were finally diagnosed by ureteroscope examination. The negative imaging ureterolith were broken by air pressure ballistic curve shock wave,and taken out of ureter by ureteroscope. All cases were put double-J in ureter. Results Thirty-six cases were got success relieves of ureter obstruction in 24 hours. The urine volume of them were increased, symptoms of urinemia were disappeared, BUN and creatinine were normal after operations. Conclusions The treatment and diagnosis methods by ureteroscope for acute renal failure caused by negative imaging ureterolith are quick and safety, which can treat both side ureterolith at the same time and get reliable and safe effect with less trauma. It should be the first choice to treat acute renal failure caused by negative imaging ureterolith.
ABSTRACT
Objective To evaluate the safety and efficacy of nephron sparing surgery (NSS) for renal angiomyolipoma (RAML). Methods Thirty-nine patients of RAML were underwent NSS. Tumor enucleation was done in 23, partial nephrectomy in 16, and selective arterial embolization in 2. Results The average diameter of enucleated tumor was 5.8 cm(from 3.0 to 14.0 cm), the average of blood loss was 190 ml(from 75 to 800 ml),none of the patients developed hemorrhage or urinary fistula. The average follow-up of 38 patients was 48 months(from 1 to 120 months). Postoperative serum level of creatinine was stable, no patients had a local recurrence. Conclusions NSS can be performed with satisfactory result in RAML. Effective control of hemorrhage and conservancy of renal function are the key points.
