Anastomosing hemangioma (AH), a rare benign vascular tumor, is a newly recognized variant of capillary hemangioma. In the microscopic examination, this tumor has characteristic feature of the unique anastomosing sinusoidal capillary sized vessels. It can be misdiagnosed as a malignancy such as renal cell carcinoma or angiosarcoma. Herein, we report a case of AH originating in the right kidney of a 43-year-old man, which was initially considered as cystic renal cell carcinoma on computed tomography (CT). The patient underwent laparoscopic radical nephrectomy, but pathologic result was AH of the kidney. There was no evidence of recurrence or metastasis 5 months after the surgery.

Hem-o-Lok clips (Weck Surgical Instruments, Teleflex Medical, Durham, NC, USA) are widely used in robot-assisted laparoscopic radical prostatectomy because of their easy application and secure clamping. To date, there have been some reports of intravesical migration of these clips causing urethral erosion, bladder neck contractures, and subsequent calculus formation. We report the first case of bladder migration of Hem-o-Lok clips without stone formation after robot-assisted laparoscopic radical prostatectomy. The Hem-o-Lok clips were found during urethral dilation with a guide wire for bladder neck contracture under cystourethroscopy. The Hem-o-Lok clips were floating in the bladder without stone formation and were removed by a cystoscopic procedure.

PURPOSE: Increasing evidence suggests that Randalls plaque contributes to the pathogenesis of urinary stone formation. The purpose of our study is to compare the incidence of the abnormal metabolic stone risk factors between the calcium stone former with papillary calcification and the calcium stone former without papillary calcification on unenhanced spiral computed tomography (CT). MATERIALS AND METHODS: A series of patients with calcium stones (n=49) underwent unenhanced spiral CT and complete metabolic evaluation after they consumed a random diet for 1 month after stone removal. Of the 49 patients, 38 patients showed papillary calcification on unenhanced spiral CT and 11 patients did not. Their blood was evaluated by using a multichannel analysis sequential multichannel autoanalyzer (SMA)-20 and PTH tests. The 24-hour urinary constituents were assayed for calcium, oxalate, citrate, total volume, phosphorus and sodium. We compared the incidence of abnormal metabolic risk factors between the two groups. Statistical analysis was performed by chi-square tests. RESULTS: The incidences of hyperuricemia were 27.3% in the patients without papillary calcification and 31.6% in the patients with papillary calcification. The incidences of hypernatriuria were 18.2% versus 42.1%, the incidences of hypercalciuria were 36.4% versus 26.3%, the incidences of hyperuricosuria were 18.2% versus 18.4%, the incidences of hyperoxaluria were zero versus 28.9%, and the incidences of hypocitraturia were 45.5% versus 44.7%, respectively. The difference between the two groups was statistically significant only for hyperoxaluria (p=0.043). CONCLUSIONS: Hyperoxaluria is the only metabolic risk factor that more frequently occurred in the patients with papillary calcification. Our date suggest that hyperoxaluria may be an important factor in the pathogenesis of papillary calcification.

A 75-year-old female visited our hospital with bilateral adrenal masses that were detected incidentally during lumbar spine magnetic resonance imaging (MRI) for the evaluation of radiating flank pain. Consecutive computed tomography and MRI revealed bilateral adrenal masses with no evidence of lymph node enlargement or local invasion; 2[(18)F]fluoro-2-deoxyglucose (FDG)-positron emission tomography showed an intense FDG accumulation in both adrenal glands without abnormal FDG uptake in extra-adrenal regions. The laboratory test results were within normal ranges. We performed a bilateral adrenalectomy. The pathologic diagnosis of both adrenal masses was consistent with adrenocortical carcinoma. The patient recovered well with no complications.

Calciphylaxis has been described as a rare condition in patients with end-stage renal disease and secondary hyperparathyroidism. Selye et al. first coined the term calciphylaxis to describe soft-tissue calcification and cutaneous necrosis. The common manifestation include painful digital necrosis and medial calcification of small and medium sized vessels. Calciphylaxis is a clinical diagnosis and is characterized by painful, violaceous, mottled skin lesions. Radiographic studies reveal calcification of median and small vessels under the knee but vascular calcification is not specific for calciphylaxis. Histolopathologic findings show a markedly reduced lumen, secondary to the fibrin deposition and inflammation in and around the outer media with an outer ring of calcification which leads to progressive ischemic tissue necrosis. Kidney transplantation and parathyroidectomy is recommened but it is controversial. We present the case of a 64-years-old man with chronic renal failure as well as painful ischemic necrosis on the lower extremity. The pertinets literature is reviewed.

Adrenal myelolipoma is a rare, nonfunctional benign tumor that is composed of mature adipose tissue and hematopoietic elements. In the past, these tumors were accidentally discovered at autopsy. Today, they are found much more frequently and incidentally, mainly because of the widespread use of noninvasive imaging with ultrasonography, computed tomography, and magnetic resonance imaging. Most lesions are asymptomatic, small, and unilateral, but a number of bilateral tumors have been reported. We report here on a case of a 48-year-old man with incidentally found myelolipomas of both adrenal glands. In particular, a giant myelolipoma of the left adrenal gland was treated by transperitoneal laparoscopic adrenalectomy.

PURPOSE: As recently reported, the short-term results of the tension-free vaginal tape SECUR(R) (TVT-S) procedure seem to be similar to those of the conventional transobturator tape (TOT) procedure. However, results of efficacy and satisfaction with TVT-S are insufficient in patients with more than 1 year of follow-up. Therefore, we evaluated the results of the TVT-S procedure in women with stress urinary incontinence (SUI) during 2 years. MATERIALS AND METHODS: We evaluated 51 patients with clinical and urodynamic diagnoses of SUI who underwent the TVT-S procedure from March 2008 to February 2009. Preoperative evaluation included a history, cough stress test with full bladder, urodynamic study, and incontinence quality of life (I-QoL) questionnaire. Following the postoperative period, urinary incontinence status was examined through a physical examination and the I-QoL questionnaire was completed in an outpatient setting or by telephone. RESULTS: Data from 2 years of follow-up were available for 46 of 51 patients. The cure rate was 80.4% at 1 month after TVT-S and 76.0% at 2 years after TVT-S. The cure or improvement rate was 93.5% at 1 month after TVT-S and 86.8% at 2 years after TVT-S. The mean total I-QoL score increased by 42 points at 1 month after TVT-S (p<0.026) and by 32 points at 2 years after TVT-S (p<0.013). Most patients reported significant improvements in quality of life. At the 2-year follow-up, there were no significant complications related to TVT-S. CONCLUSIONS: The results of this study suggest that TVT-S is an efficient and safe procedure for the improvement of both the quality of life of the patients and the SUI itself.

Many congenital dysplasias of the osseous labyrinth have been identified, and the differential diagnosis of these dysplasias is essential for delivering proper patient management. We retrospectively reviewed the computed tomography (CT) and magnetic resonance (MR) imaging findings of 20 children who had congenital sensorineural hearing loss. The children included cases of enlarged vestibular aqueduct and endolymphatic sac (n=8), aplasia of the semicircular canal (n=4), lateral semicircular canal-vestibule dysplasia (n=3), common cavity malformations with a large vestibule (n=1), cochlear hypoplasia (n=1), Mondini's dysplasia with large vestibular aqueduct (n=1), Mondini's dysplasia with a large vestibule (n=1), and small internal auditory canal (n=1). Six cases were unilateral. Nine cases had combined deformities, and nine cases had cochlear implants. CT was performed with a 1.0-mm thickness in the direct coronal and axial sections with using bone algorithms. MR was performed with a temporal 3D T2 FSE 10-mm scan and with routine brain images. We describe here the imaging features for the anomalies of the inner ear in patients suffering from congenital sensorineural hearing loss.

Seminal vesicle cysts associated with ipsilateral renal agenesis are very rare, with most being congenital, and two-thirds associated with renal dysplasia or agenesis and ectopic ureter opening into the seminal vesicle. When they are symptomatic, surgical excision has been the treatment of choice. Herein, a case of a symptomatic giant seminal vesicle cyst associated with ipsilateral renal agenesis is reported, which was treated by laparoscopic excision.
