[Experience in the clinical application of semirigid mini-urethral endoscopes in the diagnosis and treatment of urinary bladder diseases]. / Opyt klinicheskogo primeneniia poluzhestkikh miniureterorenoskopov v diagnostike i lechenii mochekamennoi bolezni.

We compared efficacy and safety of clinical application of modern semirigid miniureterorenoscopes (MURS) and standard hard-lens ureterorenoscopes (URS). The results of 335 transurethral endoscopic operations on the ureter have been analysed. Positive results of ureteroliths elimination by lithotripsy and lithoextraction were observed in 100 (77.5%) patients of group 1 (hard-lens URS) and in 175 (94.6%) patients of group 2 (semirigid MURS). Ureteral perforation occurred 3 times more often in group 1 patients than in group 2 (3.1 and 1.08%, respectively). A total number of complications observed in group 1 and 2 in the course of transurethral ureterolithotropsy and lithoextraction reached 6.3 and 1.08%, respectively. Ureterolithotomy was performed in group 2 eight times less frequently than in group 1 patients (2.1 and 17.9%, respectively). Ureteropyeloscopy made by semirigid MURS is a valuable therapeutic and diagnostic aid which raises efficacy of transurethral endoscopic manipulations, significantly lowers traumaticity of the upper urinary tracts and reduces to minimum the number of intra- and postoperative complications.

[Percutaneous paracentric nephrostomy in infants]. / Chrezkozhnaia punktsionnaia nefrostomiia u detei grudnogo i iasel'nogo vozrasta.

The paper describes the technique of transcutaneous paracentetic nephrostomy in infants, emphasizes advantages of this method in infants versus the others used to correct supravesical obstruction (open nephrostomy, ureterocutaneostomy, kidney catheterization, internal stenting), describes relevant indications. The nephrostomy was performed in 16 infants. The results show effectiveness and safety of this method.

[Treatment of solitary renal cysts in children]. / Lechenie prostykh kist pochek u detei.

The authors formulate therapeutic policy basing on clinical, ultrasound and parenchymal morphological studies in 34 children with solitary renal cysts. Operative intervention is indicated in renal function decline manifesting with enlargement of the cyst and reduction of the cystic-renal coefficient. The kind of the operation is decided by location of the cyst and its characteristics obtained at radiodiagnosis. In slow growth of the cyst and no further decline in its function the patients should be followed up as a risk group.
