Objective: To evaluate the effects of terazosin and tolterodine on ureteral stent discomfort. Materials and Methods: Of 163 patients assessed for eligibility, 104 patients were randomly assigned to receive placebo, 2 mg of terazosin twice daily, 2 mg of tolterodine daily, or both terazosin plus tolterodine during the stenting period. Prior to stenting and at stent removal, the International Prostate Symptom Score (IPSS), the IPSS quality of life (QoL) subscore and the Visual Analog Scale for Pain were determined. The patients also reported their analgesic use during the stenting period. Results: Ninety-four patients completed the study. We noted significant decreases in the total IPSS scores (p = 0.002), irritative subscore (p = 0.039), QoL (p = 0.001), flank pain (p = 0.013), voiding pain (p = 0.01) and amount of analgesics used (p = 0.02) in the groups. However, neither the obstructive subscore nor the suprapubic pain improved significantly (p = 0.251 and p = 0.522, respectively). The patients receiving terazosin plus tolterodine experienced significant reductions in the total IPSS, irritative symptoms, QoL, flank pain, voiding pain and decreased analgesics use compared with those patients receiving placebo. However, compared with placebo, terazosin monotherapy did not affect pain levels, and tolterodine monotherapy did not improve QoL, flank pain or analgesics use. Conclusions: Terazosin plus tolterodine improves ureteral stent-related complications, including irritative symptoms, the amount of analgesics used, QoL, flank pain and voiding pain but does not decrease obstructive symptoms or suprapubic pain. This trial was registered at www.clinicaltrials.gov as NCT01530243.
PurposeTo evaluate the effect of tolterodine on early storage symptoms following transurethral resection of the prostate.Materials and MethodsSeventy patients over 55 years of age who underwent transurethral resection of the prostate owing to benign prostatic hyperplasia were randomly assigned to receive either 2 mg of tolterodine twice daily (treatment group) or matched placebo during a 1-month study period. Before and 1 month after the procedure, they were asked to complete the International Prostate Symptom Score (IPSS) questionnaire and quality of life subscale to assess their symptoms. Also, analgesic use and adverse drug events were determined at follow-up.ResultsOf 70 allocated patients, 64 patients (91.4%), including 33 in the treatment group and 31 in the placebo group, completed the study. The mean age of the patients was 67 years. None of the patients' basic clinical characteristics were significantly different. At the end of the follow-up period, the total IPSS and quality of life score had significantly improved in the patients receiving tolterodine compared with those receiving placebo (p=0.001 and p=0.036, respectively). The treatment group compared with placebo demonstrated significant improvements in frequency and urgency but not in nocturia. The amount of consumed painkiller was also significantly lower in the tolterodine group than in the placebo group (p=0.0001). The rate of side effects was not significantly different between the groups.ConclusionsAdministering 2 mg of tolterodine twice daily is an effective and well-tolerated regimen to relieve early storage symptoms, quality of life, and the amount of analgesic consumption following transurethral resection of the prostate.
Adrenocortical carcinoma (ACC) is a rare aggressive tumor. Renal vein and inferior vena cava (IVC) thrombi have been found as uncommon presentations of ACC; however, the implementation of comprehensive therapy has remained controversial in such cases. We report a case of a 46-year-old woman with a large ACC associated with the invasion of tumor to IVC confirmed by imaging and immunohistochemistry examinations. The patient was treated successfully using aggressive surgery, including adrenalectomy and thrombectomy adjunct to an adrenocorticolytic agent. However, she died of metastasis complications at 3-month follow-up period. ACC is a rare malignancy, mostly presenting in advanced stages with poor prognosis. Implementing aggressive surgical therapy might be effective for the management of such cases; however, the short survival duration in our case underscores the need for defining the precise therapy of metastatic ACC associated with venous invasion.
Objective:The aim of this investigation was to assess the efficacy of hydrochlorothiazide as a hypocalciuric diuretic on stone-free rate of renal pelvic calculi after extracorporeal shock wave lithotripsy (ESWL).Materials and Methods:A double-blind, placebo-controlled randomized clinical trial was conducted and 52 patients with renal pelvic calculi (diameter ≤2 cm) were enrolled from February 2010 to September 2010. ESWL protocol was performed by 2,500 shocks per session. The patients were randomized into two groups: (1) 26 patients who were given 25 mg hydrochlorothiazide twice daily; and (2) 26 patients who received placebo. The stone-free rate was defined as residual calculus size ≤4 mm in controlled ultrasound on 2nd week, 1 month and 3 months after ESWL.Results:19 (78%) of the first group and 9 (42.9%) of the second group were stone-free after one session of ESWL (P = 0.02). 88% of the group 1 and 47.8% of the group 2 were stone-free on 1 month after ESWL (P = 0.003); however, this effect of hydrochlorothiazide was not related to the patients' body mass index, age and gender. The accessory treatment procedures were applied in 24% of the group 1 compared with 19% of the group 2 during 3 months (P = 0.68). All patients in both groups were stone-free on 3 months following lithotripsy.Conclusions:Hydrochlorothiazide did not impact on the stone-free rate and using accessory procedure within 3 months; however, it decreased duration of stone-free status and number of ESWL sessions.
PurposeTo assess the efficacy of percutaneous unroofing in the treatment of simple renal cysts instead of laparoscopic decortication and open surgeries.Materials and MethodsFrom November 2009 to October 2010 at our department, 11 patients with 12 simple cyst units were managed by percutaneous unroofing. All cysts were evaluated with ultrasonography and abdominal computed tomography. If there were no contraindications, cyst wall resection was performed. A standard transurethral resectoscope was used to resect the cyst wall, and the parenchymal portion of the cyst was subsequently cauterized. The drain was left in place for 2 days.ResultsAt the 5-month follow-up, patients were asked about their symptoms and ultrasonography was performed. From 12 cyst units, 8 were completely resolved, 3 were reduced to less than 50%, and 1 was persistent to near its original size. Success was defined as a more than 50% reduction in cyst volume.ConclusionsSimple renal cysts can be safely managed by percutaneous unroofing with a success rate of more than 90%. This technique can offer several advantages over open surgery, such as decreased length of hospital stay, improved convalescence, and reduced risk of complications. Percutaneous resection also avoids the multiple trocar sites, extensive dissection, and technical difficulty associated with laparoscopy.
