PURPOSE: Extracorporeal shock wave lithotripsy (SWL) has been established as the treatment of choice for the urinary stones. But, for the treatment of staghorn calculi, the efficacy of this therapeutic procedure is controversal. We intended to study the therapeutic results and the usefulness of ureteral stent between 2 types of lithotriptor, EDAP LT-01 and Storz Modulith SLX. MATERIALS AND METHODS: Sixty cases were diagnosed as staghorn calculi from February 1990 to December 1998. Among them, 31 patients were treated with EDAP LT-01 SWL (group A) and 29 patients with Storz Modulith SLX SWL (group B). We inserted a double-J stent in 45 patients that consisted of 24 patients from group A and 21 patients from group B. The number of treatment sessions, complications and success rates were compared regarding each SWL and volume of the stone. RESULTS: The success rates of each SWL were 70.9% in group A and 75.9% in group B. The success rates, according to staghorn morphology, were 71.4% and 85.7% in partial staghorn of group A and B. The average shock wave sessions were 12.0 and 7.4 in partial staghorn of group A and B. The success rates, according to staghorn volume, were 67.8% and 88.9% in less than 60cm3 of group A and B. The average shock wave sessions were 12.6 and 9.6 in less than 60cm3 of group A and B. The findings were statistically significant between the two groups in less than 60cm3 or partial staghorn. After SWL, incidence of steinstrasse was 12.5% and 33.3% in the double-J stent inserted patients of group A and B. CONCLUSIONS: SWL could be a method of primary treatment for staghorn calculi. Storz Modulith SLX SWL was more effective than EDAP LT-01 SWL for staghorn calculi of which the volume was less than 60cm3. Placement of ureteral stents would be effective in the treatment of staghorn calculi by EDAP LT-01 SWL and not in Storz Modulith SLX.

Bronchogenic cysts are rare congenital malformations, most often occurring in the pulmonary parenchyma or posterior mediastinum. But they can develop in the ectopic area, especially in the retroperitoneal space. We report a case of adrenal bronchial cyst treated with laparoscopic excision. A 55-year-old woman was admitted with a left adrenal tumor on computed tomography during a study for dyspnea, cough, and sweats. The function of the adrenal glands was examined, and as a result, the adrenal tumors were determined to be nonfunctional. Magnetic resonance imaging showed about an 8-cm-sized large unilocular cystic lesion with mild and high signal intensities at left suprarenal fossa on T1 and T2 images. Iodine-123 metaiodobenzylguanidine scan showed no scintigraphic evidence of neuroendocrine tumor in the left adrenal gland. We performed laparoscopic adrenalectomy with transperitoneal approach. The round, cystic mass was completely excised saving normal adrenal tissues. The operative time was 75 minutes and there was no definitive bleeding and complication. The pathologic tissue weighed 35 g and measured 88 mm×45 mm×28 mm, and cystic changes were observed on the cut surface. The pathologic examination confirmed an adrenal bronchogenic cyst. We report a very rare disease, adrenal bronchial cyst, which could be easily and safely treated with laparoscopic surgery.

When surgical treatment for symptomatic seminal vesicle cyst is deemed necessary, conventional surgery is invasive because of the deep location and dissection difficulty of the seminal vesicles in the retrovesical space. Recently, the laparoscopic approach has been advocated as an optimal yet minimally invasive technique for the surgical treatment of seminal vesicle pathology. It provides a good image and easy approach to the seminal vesicles. We report a case of a symptomatic giant cyst of the left seminal vesicle that is associated with ipsilateral renal agenesis, which was treated by transperitoneal laparoscopic excision.

PURPOSE: During transrectal ultrasound guided prostate biopsy, 65% to 90% of patients reportedly have discomfort. We compared the anesthetic effects of a periprostatic injection of lidocaine under ultrasound guidance with the effects of a rectal instillation of lidocaine gel before the transrectal ultrasound guided prostate biopsy. MATERIALS AND METHODS: A prospective randomized double-blind study was performed in 72 patients requiring a systematic biopsy of the prostate. Patients were randomized into two groups according to the method of anesthetic delivery that was used. Group 1 consisted of 37 patients who intrarectally received 10 ml of 2% lidocaine gel 10 minutes before biopsy, and 5 ml of normal saline was injected into the periprostatic nerve plexus just before biopsy under ultrasound guidance using an 18 gauge 16 cm needle on each side. Group 2 consisted of 35 patients who received 10 ml of sterile gel without lidocaine and a 5 ml 1% lidocaine injection using the same method as group 1. The pain score was assessed using a visual analogue scale immediately after biopsy. RESULTS: There was a statistical difference in the mean pain score between the two groups (5.1+/-1.7 in group 1 versus 3.3+/-1.5 in group 2) (p<0.001), but The complication rates were not significantly different. CONCLUSIONS: We believe that performing the transrectal ultrasound guided prostatic nerve blockade before biopsy significantly diminishes the discomfort associated with the procedure, which, in turn, improves patient tolerance more so than rectal instillation of lidocaine gel. In addition, this procedure is a safe, simple, and rapid technique that should be considered in all patients undergoing transrectal ultrasound guided prostate biopsy.

Renal vein thrombosis is a rare, renal disease in adults that is related to hypercoagulability. We experienced a case of renal vein thrombosis in a 30-years old woman who presented with fever, chills and left flank pain after delivery. She was treated with catheter-directed thrombolytic therapy and oral anticoagulants.

PURPOSE: We studied how to increase the detection rate of prostatic cancer in men with normal DRE and the diagnostic gray zone of PSA in whom transrectal prostate biopsies were done. MATERIALS AND METHODS: We analyzed 132 patients with normal DRE and serum PSA greater than 4ng/ml, in whom transrectal prostate biopsies were done between January 1, 1996 and July 31, 2000. These patients were divided into two groups, one group having normal DRE and serum PSA level between 4 and 10ng/ml, in whom transrectal prostate biopsies was done and another group having normal DRE and serum PSA level between upper limit of age-specific PSA reference ranges (APSA-R) and 10ng/ml, in whom transrectal prostate biopsies was done. We applied PSAD and F/T PSA ratio to each group. RESULTS: Eighty-one patients with serum PSA level between 4 and 10ng/ml and 67 patients with serum PSA level between upper limit of APSA-R and 10ng/ml, underwent prostate sextant biopsies. In each group, prostate cancer detection rates were 7.4% and 7.5%. When we applied F/T PSA ratio cut off of 0.15 in each group, prostate cancer detection rates were 19.4% and 22.7%, individually (p<0.05). CONCLUSIONS: Application of F/T PSA ratio can be used significantly to elevate the detection rate of prostate cancer and reduce safely the number of biopsies performed in patients with gray zone of serum PSA levels.

PURPOSE: Renal vascular clamping during a laparoscopic partial nephrectomy is a time-consuming procedure with a risk of renal ischemia. To study the feasibility of laparoscopic partial nephrectomy without renal arterial clamping, we compared the procedure with laparoscopic partial nephrectomy with vascular clamping. MATERIALS AND METHODS: Seventeen patients underwent laparoscopic partial nephrectomy without renal arterial clamping (group 1) from February 2004 to June 2008. The operative results were reviewed retrospectively and compared with those of 16 patients who underwent laparoscopic partial nephrectomy with arterial clamping (group 2). Patient characteristics did not differ significantly between the 2 groups. However, exophytic tumors were detected in 13 patients in group 1 and 3 patients in group 2 (p=0.001). Scores on the preoperative aspects and dimensions used for an anatomical (PADUA) classification were 6.9 in group 1 and 7.7 in group 2 (p=0.037). All surgeries by the transperitoneal approach were performed by a single surgeon. RESULTS: The mean operative times were 103 and 130 minutes in groups 1 and 2, respectively (p=0.312). The mean renal arterial clamping time of group 2 was 27.6 minutes (range, 20-42 minutes). The mean estimated blood loss was 327 ml in group 1 and 315 ml in group 2 (p=0.971). The mean postoperative change in the glomerular filtration rate was 20.11 ml/min/1.73 m2 in group 1 and 18.95 ml/min/1.73 m2 in group 2 (p=0.748). The mean times to postoperative initiation of ambulation and of oral intake were 1.6 and 1.7 days (p=0.486) and 1.3 and 1.6 days (p=0.811) in groups 1 and 2, respectively. The mean length of hospital stay was 7.4 and 7.9 days in groups 1 and 2, respectively (p=0.9). The mean tumor size was 2.1 cm (range, 1-7 cm) in group 1 and 3.3 cm (range, 1.5-9 cm) in group 2. CONCLUSIONS: Laparoscopic partial nephrectomy without renal arterial clamping is feasible for a localized renal tumor. However, patients should be selected carefully, such as those with an exophytic tumor.

PURPOSE: Reports of clinical findings and treatment for pediatric urinary stone have been published relatively infrequently. Extracorporeal shock-wave lithotripsy (SWL) is a minimally invasive method of treating urinary stone and has been shown to be effective in the pediatric population. We evaluated the clinical characteristics of patients with pediatric urinary stone and compared the therapeutic results of two SWLs, LT-01+ and Modulith SLX lithotriptors. MATERIALS AND METHODS: The records of 57 children treated by SWL were analyzed retrospectively. Twenty-five patients were treated by LT-01+ (group I) and 32 by Modulith SLX (group II) lithotriptor. The outcomes, including the number of treatment sessions, stone free rate and complications, were assessed. RESULTS: The average age of all 57 children, 36 male and 21 female, was 14.3 years. Chief complaints were flank pain (71.9%), gross hematuria (10.5%) and urinary tract infection (12.3%). The average stone size was 8.2mm (2-15mm). The success rates of each SWL were similar in both groups (group I: 88.0%, group II: 90.6%). However the average number of treatment sessions/patient in Group I was significantly smaller than that of Group II (group I: 2.92, group II: 1.35, p<0.05). Flank pain and gross hematuria were developed similarly after treatment in both groups, and needed only conservative therapy and was resolved within three days. CONCLUSIONS: Clinical characteristics of urinary stone in children were similar to those of adults. There was no significant difference in treatment success rate between the two types of lithotriptors but the number of treatment sessions was smaller in patients treated by Modulith SLX lithotriptor.

PURPOSE: Some authors have suggested that erectile dysfunction correlates with the level of glycemic control and glycosylated hemoglobin can be used to predict erectile dysfunction in diabetic patients. This study evaluated whether or not glycosylated hemoglobin level can predict the effectiveness of sildenafil citrate, which is a first line therapy for erectile dysfunction. MATERIALS AND METHODS: A consecutive sample of 32 men with type 2 diabetes and erectile dysfunction completed the International Index of Erectile Function (IIEF) and had their glycosylated hemoglobin levels measured. 50mg of sildenafil citrate was prescribed at the first visit, which was then increased to 100mg if the symptom persisted. According to the response, the patients were divided into responders and nonresponders. The pretreatment clinical parameters (age, diabetic duration, erectile dysfunction duration, glycosylated hemoglobin level, body mass index, IIEF, diabetic complications, smoking, alcohol drinking) were recorded. The patients were divided into 3 groups according to the drug dosage (group 1 was 50mg responders, group 2 was 100mg responders, group 3 was nonresponders in any dosage) and the clinical parameters were compared and analyzed. RESULTS: The mean hemoglobin A1c level was 8.68 0.74% and 7.64 1.67% in the nonresponders and responders (p < 0.05), respectively. Diabetic neuropathy and diabetic retinopathy were significantly higher in the nonresponders (p < 0.05). The mean hemoglobin A1c levels of the three groups were 7.36 1.01, 7.78 0.98, and 8.64 0.44%, respectively and group 3 was significantly higher than the other groups (p < 0.05). CONCLUSIONS: High levels of glycosylated hemoglobin suggests a poor response to sildenafil citrate in diabetic patients with erectile dysfunction. Diabetic patients with neuropathy or retinopathy may have a low response for sildenafil citrate.

Malakoplakia is a chronic inflammatory disease. Approximately 75% of cases are located in the genitourinary system. The etiology remains obscure but it appears related to an underlying infection. It mainly occurs in females in a 4:1 ratio, and the peak age is in the sixth decade. Apart from the symptoms associated with urinary tract infections, the clinical manifestations are usually unremarkable. Here, we report a 44-year-old woman suffering from an intraabdominal mass, with histology that was specific for a malakoplakia of the bladder. This case was difficult to differentiate from a urachal cancer.
