RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

A ruptured bladder, or extravasation from the bladder, is almost always associated with trauma. Spontaneous extravasation, or iatrogenic extravasation, is extremely rare, with only few reported cases. Herein, two cases of bladder rupture, which occurred during voiding cystourethrography (VCUG), one in an 18 month old patient and the other in a 6 week old patient, due to instill dye by high pressure, are presented.

RESUMEN

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.

RESUMEN

PURPOSE: The aim of this study was to assess whether there was an association between lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) in men. MATERIALS AND METHODS: 79 patients who had LUTS, between January 2002 and July 2004, were randomly retrospectively analyzed. LUTS and ED were assessed by validated symptom scales, including the International Prostate Symptom Score (IPSS), the Danish Prostate Symptom Score1 (DAN-PSS1) and the International Index of Erectile Function (IIEF). The patients were divided into three group according to age; younger than 60 (group I), 60 to 69 (group II), and 70 years or older (group III). RESULTS: The mean age was 62.6+/-9.19 years. Prevalence rate of mild, moderate and severe LUTS were 12.9, 67.7 and 19.4% in group I, 8.3, 58.3 and 33.4% in group II, and 16.6, 54.2 and 29.2% in group III, respectively. The mean IIEF scores by IPSS according to the severity were 39.8, 38.4 and 28.7 in group I and 54.5, 39.8, and 24.3 in group II and 29.5, 16.5 and 15.6 in group III, retrospectively. In each group, the IIEF score decreased with increasing IPSS, LUTS was also shown to be statistically significantly correlated with the presence of ED (p=0.028). No statistical significance was found between the IPSS and DAN-PSS1 (p=0.740). CONCLUSIONS: These results suggested that ED was highly prevalent among patients with LUTS, and erectile function should be evaluated in the patients with LUTS for the management of ED and to improve the quality of life of these patients.

RESUMEN

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.
