Kidneys are very common sites of cysts in the human body, prevalence of renal cysts was estimated to be about 10% in the general population and the incidence increases with age. Parapelvic and peripelvic cysts grow near renal collecting system; these types of cysts are most likely to be symptomatic. There are a number of reports describing successful laser incision drainage of parapelvic cysts ...

Ultrasonography is the primary imaging tool for a patient considered to have an ovarian cyst. On a sonogram, simple ovarian cysts have a uniformly thin, rounded wall and a unilocular appearance that is either hypoechoic or anechoic. They usually measure 2.5-15 cm in diameter, and posterior acoustic enhancement (a hyperechoic area) may be visible deep to the fluid-filled cyst. Most commonly, the...

PURPOSE To describe our initial experience with radiofrequency ablation (RFA) of Bosniak IV renal cysts. MATERIALS AND METHODS From 2010 to 2014, 154 renal tumor cases were treated with percutaneous thermal ablation, of which 10 cases (6.4%) from nine patients were complex renal cysts and were treated with radiofrequency ablation. RESULTS All complex cysts were classified as Bosniak IV (fou...

population aged > 50 years have renal cysts [5]. Most cysts are benign and asymptomatic. A palpable mass, pain from haemorrhage into the cyst, obstructive symptoms and infections are rare presentations. A simple cyst is a fluid-filled, non-neoplastic lesion; most are unilocular, contain straw-coloured fluid, arise from the cortex and are smooth-walled. On CT they are sharply marginated, round, ...

PURPOSE To identify size criteria for complex cystic renal masses that can distinguish renal cell carcinoma from benign cysts supplementing the Bosniak classification. MATERIALS AND METHODS We reviewed the records of 97 patients who underwent surgery for complex cystic renal masses from January 2001 to April 2010. The pathological results were compared with the lesion sizes measured by preope...

INTRODUCTION Our aim was to evaluate the result of simple renal cyst ablation by endoscope and compare the results with other techniques of renal cyst treatment. MATERIALS AND METHODS A prospective study was performed at Shaheed Faghihi hospital from January 2001 to January 2003. Ten patients with symptomatic simple renal cyst were selected for this study. The exclusion criteria were history ...

Cystic renal neoplasms and renal epithelial stromal tumors are diagnostically challenging and represent some novel tumor entities. In this article, clinical and pathologic features of established and novel entities are discussed. Predominantly cystic renal tumors include cystic nephroma/mixed epithelial and stromal tumor, synovial sarcoma, and multilocular cystic renal cell carcinoma. These ent...
