MORPHOLOGICAL CHANGES OF RENAL STAGHORN NEPHROLITHIASIS.

Morphological changes in the kidneys of patients with staghorn nephrolithiasis at the time of endoscopic surgery staghorn calculi. In all cases, the morphological study of biopsy specimens revealed varying degrees of renal parenchyma lesions that may be predictors of chronic renal failure in patients with staghorn nephrolithiasis. Assessment of the extent of damage of the renal parenchyma is necessary for the timely implementation of renoprotective therapy.

DISTINCT FEATURES OF STAGHORN NEPHROLITHIASIS IN SOUTH OF RUSSIA

A study of staghorn nephrolithiasis pathogenesis with aim of stone prevention has particular importance. Knowledge of urine stones’ chemical structure is a basic in individual metaphylaxis. A complex biochemical analysis of blood and 24-hours urine for mineral disturbances detection in 136 patients with staghorn stones was performed. An x-ray analysis for detection a mineral structure of 130 stones was done. An analysis of chemical structure of stones and blood biochemical disturbances showed the typical changes of metabolism in specific stones only in 56,9% cases, which make an understanding of processes underlying stone formation more complicated.

Complications of minimally-invasive percutaneous nephrolithotomy

To evaluate the occurrence and management of complications following minimally invasive percutaneous nephrolithotomy (MPCNL). The data of 4326 cases of MPCNL from January 2001 to February 2006 were reviewed, including 2451 male cases and 1875 female cases. Their age ranged from 4 to 82 years with a mean of 42 years. Of 4326 cases, 1221 cases had simple nephrolithiasis, 1735 staghorn nephrolithiasis, 386 upper ureterolithiasis, 90 serious stone street after extracorporeal shock wave lithotripsy, and 894 residual calculi after open surgery. Among the 4326 cases of MPCNL, complications occurred in 445 cases (10.3%). Of the 445 cases, 20 had massive hemorrhage, 13 pleural injuries, 1 colonic perforation, 343 fever attacks (T > 38 degrees C), 13 septic shocks, 16 perinephric urinoma, 9 perinephric abscess, 26 renal perforating injuries, 1 guide wire misled into inferior vena cava, 3 died. MPCNL is a minimally invasive operation. However, serious complications would occur if the procedure were ignored. The improvement in the prevention and management of complications can promote the application of this procedure.

Analysis of treatment in Sickle renal parenchyma incision for the removal of complex staghorn renal stone

目的 探讨镰刀状肾实质切开术治疗复杂性鹿角状肾结石的疗效.方法 采用镰刀状肾实质切开术和无萎缩性肾切开取石术治疗复杂性鹿角状肾结石各20例.比较两组手术时间、术中出血量和并发症发生情况.结果 两组手术均顺利完成.平均手术时间治疗组为(123±35)min;对照组为(152±28)min.平均术中出血量治疗组(130±60)ml;对照组(200±72)ml.结石残留两组各有3例.术后大出血治疗组1例,对照组3例.结论 镰刀状肾实质切开取石术有手术时间较短,术中出血少,术后大出血发生率小等优点,较适用于治疗复杂性鹿角状肾结石。

Nephrobronchial fistula secondary to xantogranulomatous pyelonephritis

We report a case of staghorn nephrolithiasis that evolved into xanthogranulomatous pyelonephritis with perinephric abscess, nephrobronchial fistula, and lung abscess. The patient was an intravenous drug abuser who tested positive for human immunodeficiency virus, without evidence of acquired immunodeficiency syndrome. He presented with a 2-month history of untreated repeated episodes of left flank pain and hyperpyrexia. Treatment involved left nephrectomy, debridement of abscess, tube drainage, and intravenous antibiotics. The patient illustrates the need to consider untreated nephrolitiasis as a predisposing factor for pulmonary complications.
