ABSTRACT Objectives: To investigate the characteristics of cases of NIH category I acute prostatitis developed after transrectal prostate biopsy and clarifiy the risk factors and preventive factors. Materials and Methods: We retrospectively reviewed the medical records of 3.479 cases of transrectal ultrasound-guided needle biopsies performed with different prophylactic antibiotherapy regimens at two different institutions between January 2011 and February 2016. The patients of Group I have received ciprofl oxacin (n=1.523, 500mg twice daily) and the patients of Group II have received ciprofl oxacin plus ornidazole (n=1.956, 500mg twice daily) and cleansing enema combination as prophylactic antibiotherapy. The incidence, clinical features and other related microbiological and clinical data, were evaluated. Results: Mean age was 62.38±7.30 (47-75), and the mean prostate volume was 43.17±15.20 (21-100) mL. Of the 3.479 patients, 39 (1.1%) developed acute prostatitis after the prostate biopsy procedure. Of the 39 cases of acute prostatitis, 28/3.042 occurred after the first biopsy and 11/437 occurred after repeat biopsy (p=0.038). In Group I, 22 of 1.523 (1.4%) patients developed acute prostatitis. In Group II, 17 of 1.959 (0.8%) patients developed acute prostatitis. There was no statistical difference between the two groups according to acute prostatitis rates (X2=2.56, P=0.11). Further, hypertension or DM were not related to the development of acute prostatitis (P=0.76, X2=0.096 and P=0.83, X2=0.046, respectively). Conclusions: Repeat biopsy seems to increase the risk of acute prostatitis, while the use of antibiotics effective for anaerobic pathogens seems not to be essential yet.

Purpose Ischemic priapism, which is a compartment syndrome, needs urgent treatment in order to nourish corpora cavernosa. As the first step, the aspiration of blood and/or the irrigation of the cavernosal bodies are performed to prevent fibrotic activity and secure erectile capability. While performing aspiration and irrigation, there are some risks of the procedure in which most refrained one is cardiovascular side effects of adrenergic agonists. We aimed to evaluate extracorporeal transient distal penile corporoglanular shunt technique in place of aspiration/ irrigation techniques for early ischemic priapism treatment. Materials and Methods In this transient shunt technique, a sterile closed system blood collection set (BD Vacutainer, Cat. No.: 367282; NJ, USA), which has two 21G needles, was used. The length of the needle and tubing was 19 mm. (0.75 inch) and 178 mm. (7 inches), respectively. This blood collection set was designed to be used not only for blood collection but can also be used for short term infusions (maximum 2 hours). Results Ten patients out of fifteen with early ischemic priapism were successfully treated with this transient shunt technique. The permanent detumescence achieved in the first 10 minutes in nine out of fifteen patients. No additional procedure needed after the disappearance of rigidity in successfully treated patients. The permanent detumescence achieved in the first 10 minutes in nine out of fifteen patients. Conclusions We demonstrated that this extracorporeal transient shunt technique gets some advantages over aspiration and irrigation in early ischemic priapism treatment. Our results indicate that the presented technique to be offered for the patients with an ischemic priapism episode of no more than 7 hours.

Introduction Ureteroscopy has improved from the first use of ureteroscope in the 1970's. Although the success rate increased in the last years, (1) new treatment techniques are being developed for impacted and large proximal ureter stones (2). Pneumatic lithotripsy has high efficiency with low complication rates (2). However, in case of steinstrasse and large (> 1 cm) ureter stones, fragmented small stones may obstruct insertion of a ureteroscope after initial lithotripsy. In order to triumph over this issue, multiple ureteroscopic passages and manipulations needed for extraction of these small stones by forceps or basket catheters. The overall incidence of stricture was found upto 14.2% when the fragments were removed with a grasping forceps or a basket (3). We present our technique to disperse small fragmented stones in order to contact non-fragmented rest stone. Materials and Methods Ureteral lithotripsy was performed with an 8-9.8F semirigid ureteroscope using a pneumatic lithotripter (Swiss LithoClast, EMS, Nyon, Switzerland). The stone was fragmented into small pieces as small as 2-3 mm. by pneumatic lithotripter. Eventually, these fragmented stones interfered with vision and the lithotripter to get in touch with the rest stone. After fragmenting distal part of the large stone, the ureteroscope was pulled back out of ureter. While pulling back, the operating channel was closed and irrigation fluid was flowing in order not to decrease pressure behind the stones. Simultaneously, a person tilted the operating table to about 30° in reverse Trendelenburg position. When the ureteroscope was out of ureteral orifice, the operating channel was opened and irrigation fluid was stopped. This maneuver aided decreasing pressure in the bladder more rapidly in addition to feeding tube. Stone dust and antegrade fluid flow were easily seen out of the ureteral orifice. Ureteroscope was re-inserted after 30-60 seconds. While reaching the rest of the stone, small stone dust was seen at first. Bigger stones were approximately 3-5 cm distal to the original place of the stone. When the non-fragmented rest stone appeared, there were no blocking fragmented stones. Insertion of the ureteroscope was easy and we could go on with the lithotripsy procedure. Conclusions In comparison to standard position, tilting and rapid decrease in pressure by pulling back the ureteroscope made gravity and negative pressure more effective.

PURPOSE: To investigate the effects of on-pump and off-pump coronary artery bypass grafting (CABG) on the erectile function and endothelium-derived nitric oxide (eNO) levels. MATERIALS AND METHODS: Twenty-eight consecutive patients were randomized into two groups depending on use of cardiopulmonary bypass in CABG surgery. The erectile function was evaluated by using the IIEF-5 questionnaire. The plasma eNO levels were determined at baseline and after reactive hyperemia before and after surgery. Blood was collected in one minute after cuff deflation from the radial artery on the same side. RESULTS: After CABG surgery the mean IIEF-5 score increased insignificantly over baseline from 14.8 to 15.8 (p = 0.29) and 12.4 to 14.3 (p = 0.11) after on-pump and off-pump CABG surgeries, respectively. The baseline plasma NO levels before surgery were 18.16 ± 7.63 nmol/L in on-pump and 21.76 ± 11.08 nmol/L in off-pump CABG. After reactive hyperemia the plasma NO levels were 22.14 ± 10.52 nmol/L in on-pump and 21.49 ± 9.13 nmol/L in off-pump CABG before the surgery. The difference in the plasma NO levels before surgery was not significant (p = 0.51). Two hours after surgery, the difference of the plasma NO levels at baseline (24.44 ± 12.31on-pump and 20.58 ± 6.74 nmol/L off-pump CABG) and after reactive hyperemia (35.55 ± 23.54 nmol/L on-pump and 23.00 ± 15.40 nmol/L off-pump CABG) were not significantly different from each other (p = 0.11). CONCLUSIONS: Patients who had on-pump or off-pump CABG surgeries had higher IIEF-5 scores. Nevertheless, the improvement was insignificant in both groups. Meanwhile, on-pump or off-pump CABG surgeries did not have significant effect on plasma eNO levels.

PURPOSE: Evaluate the results of urinary continence on patients who had undergone radical perineal prostatectomy (RPP) for clinically localized prostate cancer. MATERIALS AND METHODS: We analyzed the continence data of 120 patients with pathology of cT1-cT2N0M0 prostate cancer and who had undergone RPP. Continence was assessed on the day of catheter removal, at the end of the first and third month, and the first year postoperatively. The patients who were continent immediately after catheter removal were classified in the group of “immediately continent” while the patients who became continent during the 3 postoperative months were classified as “early continent.” RESULTS: Mean duration of catheterization was 10 (10-25) days. Of 120 patients, 44 (36.7%) were immediately continent. At the end of the first and third months, 65 (54.1%) and 87 (72.5%), respectively, were early continent. At the one-year follow-up, 95.3% of 107 cases whose one-year follow-up data were available were continent. When the relationship between patients’ age and continence was analyzed, it was found that the early continence rates were 77.7% (7/9), 73.3% (33/45), 73.4% (36/49), and 64.7% (11/17) in the groups of = 49, 50-59, 60-69, and = 70 years, respectively (p = 0.68). CONCLUSIONS: The majority of patients who underwent RPP rapidly regained continence within 3 months. RPP is an exceptional alternative approach for radical surgery in the treatment of localized prostate cancer.
