Three Dimensional (3D) Laparoscopic Nephron-sparing Treatment of a Huge Cystic Nephroma: A Case Report and Literature Review.

Background/aim: Cystic nephroma (CN) is a very rare, benign, renal cystic lesion, which is characterized by a usually unilateral, multicystic kidney mass. In adults it is seen more frequently in females (1:8 male-to-female ratio). The peak incidence of CN is between 50 and 60 years of age.

Long-term results after computed-tomography-guided percutaneous radiofrequency ablation for small renal tumors.

Purpose: To present the long-term results and to identify possible risk factors for recurrence after radiofrequency ablation (RFA) for renal tumors.

Patients And Methods: Thirty-one patients with a total of 39 renal tumors ranging from 1.3 to 7.

Delayed reaction to the Dacron buttress used in Stamey bladder neck suspension.

Stamey bladder neck suspension is thought to be an excellent procedure for stress urinary incontinence in selected groups of patients. However we must not ignore the complications of this procedure. We report a case of a patient who developed a delayed reaction with bladder wall erosion to the Dacron buttress used in Stamey urethropexy 19 years before.

Microscopic polyangiitis complicated by the development of prostate cancer and flutamide-induced hepatitis.

We report a case of a 65-year-old man with microscopic polyangiitis who developed prostate cancer and gastric adenocarcinoma after prolonged oral use of cyclophosphamide. Acute hepatitis with jaundice and marked increase in aminotranferases occurred after 6 months of flutamide treatment for metastatic prostate carcinoma. It is suggested that patients with vasculitis or other autoimmune disorders should avoid prolonged use of cyclophosphamide and other cytotoxic drugs in order to minimize long-term adverse effects, of which the risk of cancer is by far the most important.

Prognostic significance of thymidine phosphorylase in superficial bladder carcinoma.

Objective: We investigated the expression of thymidine phosphorylase (TP) in bladder carcinomas and assessed its prognostic significance in superficial bladder cancer samples.

Patients And Methods: We studied 142 primary bladder cancer samples immunohistochemically for nuclear thymidine phosphorylase (TPN), cytoplasmic (TPC) and stromal (TPSTR) expression. We correlated them with standard clinicopathological features (grade, stage, concurrent in situ, multiplicity, primary or recurrent status), as well with recurrence and progression.
