Primary myxoid leiomyosarcoma of renal pelvis: Case report and literature review.

Leiomyosarcoma arising from renal pelvis is a very rare disease. A patient was admitted to hospital with left renal colic due to nephrolithiasis, with a filling defect in renal pelvis that was considered to be a blood clot. Diagnosis of leiomyosarcoma was made after visual inspection and biopsy of the exophytic lesion.

[Combined laser recanalization in the prostatic region of the urethra].

A case is reported of an effective use of laser endoscopic intervention in benign prostatic hyperplasia when urethral anatomic size was small. The combined laser recanalization helped recovery of adequate non-assisted urination. Long-term outcome was favorable.

[Comparative assessment of the WHO and Gilson histological classifications of prostatic neoplasms (taking into account data of ploidy studies)].

We estimated ploidometric nuclear parameters of predominating cell population in various prostatic adenocarcinomas in using WHO vs Glison classification to define advantages of the above classifications. Ploidometry provides information on cell composition and proliferative activity of cells. We observed greater ploidity in different grades of cell atypia.

[Polyarthritis as a rare complication in BCG immunoprophylaxis of urinary bladder cancer].

Vaccine BCG instillations as immunoprophylaxis of superficial cancer of the urinary bladder (UB) are likely to entail side effects and serious complications. A rare case is reported of hypersensitivity reaction to M. tuberculosis with involvement of the joints.
