Introduction Premature ejaculation (PE) is the most common male sexual dysfunction. Monosymptomatic enuresis (ME) is nocturnal bed wetting, without any daytime symptoms. Recent clinical studies report an association between lifelong PE and ME. The purpose of this study was to compare the intravaginal ejaculatory time (IELT) between lifelong PE in men with and without ME. The goal was to determine if there is an association between the severity of ME and of IELT. Material and methods A total of 137 men with lifelong PE were included in this study. Subjects were asked if they had childhood ME. The characteristics and mean IELTs of pat . . .ients with and without ME were compared using the student's t-test, and the correlation between severity of ME and IELT was assessed with trend test. Results Of the 137 lifelong PE patients, 57 reported ME. There was a strong negative correlation in patients with ME between the severity of enuresis and IELT, with IELT being shorter in patients with severe ME. Conclusions A strong correlation between IELT and the severity of ME suggests a common underlying mechanism. Further studies are required to confirm these findings and elucidate the exact pathophysiology Daha fazlası Daha az

Objective: To evaluate the natural course of the stone disease in pediatric patients from different perspectives among which the spontaneous passage and stone recurrence rates evaluated during the follow-up. Materials and methods: A total of 142 children referring with primary urinary stone disease were evaluated and followed. All children in the study were divided into two groups with respect to the age (Group 1: 0-5 years and Group 2: 6-15 years). Children were followed with respect to spontaneous passage rates, recurrence-regrowth rates, physical as well as the renal growth rates. Results: Stone recurrence has been noted in 44% o . . .f patients in group 1, this value was 31% in group 2. Children with at least one identifiable metabolic abnormality tended to have higher recurrence rates than the others despite conservative measures. The average stone recurrence rate in children without any metabolic abnormality was 14% and nearly 50% in children with an identifiable metabolic abnormality. Conclusions: We may emphasize that due to the high recurrence and re-growth rates, all children with urinary stone disease should be followed closely with regular visits. The evaluation of metabolic risk factors in children with renal stone disease is the basis of medical treatment aimed at preventing recurrent stone events and the growth of pre-existing calculi. © 2010 Springer Science+Business Media, B.V Daha fazlası Daha az

Objective: The aim of this study was to determine the effect of indomethacin, an anti-inflammatory agent, on apoptosis and crystal deposition developing as a consequence of tubular cell injury induced by hyperoxaluria in an animal model. Materials and methods: Fifty New Zealand rabbits were divided into 3 groups. The first 2 groups were fed with hyperoxaluric diet and Group 3 was the control group with no supplementary procedure or treatment. While the animals in Group 1 were given only hyperoxaluric diet, Group 2 animals was applied indomethacin in addition to the hyperoxaluric diet. Animals were sacrificed at the early (7th day) a . . .nd late (28th day) periods and renal tis-sue specimens were sent for the pathological analysis of crystal deposition and apoptosis. Results: The presence and degree of crystal deposition were significantly less in the specimens obtained from indomethacin-treated group during both the early and late periods ( Daha fazlası Daha az

Article | 2011 | Journal of Andrology32 ( 2 ) , pp.151 - 154

The aim of this study was to evaluate the possible relationship between varicocele and saphenofemoral insufficiency in patients diagnosed with primary varicocele. A total of 70 patients with the primary diagnosis of varicocele were included into the study. A total of 30 age-matched healthy adults were also included in the study as a control group. Varicocele was diagnosed by palpation and observation of each spermatic cord in standing position before and during a valsalva maneuver. Additionally, scrotal Doppler and lower extremity venous Doppler ultrasonography were performed. Patients who were with spermatic varicose vein larger th . . .an 3.0 mm were included in the study group as a varicocele patient. At the lower extremity venous Doppler ultrasonography, a retrograde flow lasting longer than 0.5 seconds during normal breathing or at the valsalva maneuver was considered to be meaningful for saphenofemoral junction insufficiency. Thirty-six (51.35%) patients had insufficiency in saphenofemoral junction in the study group (6 [8.5%] bilateral, 30 [42.85%] unilateral) whereas 8 (26.6%) had insufficiency in the control group (2 [6.6%] bilateral, 6 [20%] unilateral insufficiency). The patients with primary varicocele had a statistically significant (P 5 .02) higher rate of venous insufficiency in their saphenofemoral junctions when compared with the control group. In the present study, the rate of saphenofemoral insufficiency has been found to be statistically higher in patients with primary varicocele compared with healthy men. Depending on the common presence of valvular insufficiency, we believe that the presence of varicocele should be investigated in the young population suffering from saphenofemoral junction insufficiency Daha fazlası Daha az

Objectives To evaluate the causes of emergent stent placement during the postoperative early period after uncomplicated ureteroscopy in 23 patients. Methods Of 276 uncomplicated ureteroscopy procedures performed for the management of ureteral calculi, double-J stent placement was necessary on an emergent basis in 23 patients because of intolerable colic pain and extreme patient discomfort. All stents were inserted within 24 hours after the procedure. Results Of the 23 patients requiring emergent stent placement, 14 were men and 9 were women. The stones had been located in the lower ureter in 11, mid-ureter in 6, and upper ureter in . . .6 patients. All patients had undergone an uncomplicated procedure with no complication evident either during or immediately after ureteroscopic stone management. The intraoperative findings for the 23 patients revealed extensive edema formation, unrecognized small stones embedded in the edematous ureteral wall, unpassed small fragments gathered at the orifice, obstructing blood clots, and kinking of the ureter. A retrospective evaluation of the operative CD recordings and radiographic findings clearly showed that a longer operative time, repeated access, management of a large stone, impacted calculi with ureteral wall edema, a mildly narrowed ureteral segment, ignored caliceal small calculi, and a recent history of urinary tract infection contributed to the need for postoperative intervention. Conclusions Ureteral catheterization, at least in the form of overnight stent placement, might prevent the formation of transient ureteral obstruction, with resultant postoperative patient discomfort and colic pain evident in selected cases. © 2011 Elsevier Inc Daha fazlası Daha az

Purpose: To compare the efficacy of RIRS and PNL in lower pole stones ?2 cm. Materials and and Methods: A total of 109 patients who underwent PNL or RIRS for solitary lower pole stone between April 2009 and December 2012, were retrospectively analyzed. Lower pole stone was diagnosed with CT scan. Stone size was assessed as the longest axis of the stone. All patients were informed about the advantages, disadvantages and probable complications of both PNL and RIRS before the selection of the procedure. Patients decided the surgery type by themselves without being under any influences and written informed consent was obtained from all . . .patients prior to the surgery. Patients were divided into two groups according to the patients' preference of surgery type. Group 1 consisted of 77 patients who underwent PNL and Group 2 consisted of 32 patients treated with RIRS. Stone free statuses, postoperative complications, operative time and hospitalization time were compared in both groups. Results: There was no statistical significance between the two groups in mean age, stone size, stone laterality, mean follow-up periods and mean operative times. In PNL group, stone-free rate was 96.1% at first session and 100% after the additional procedure. In Group 2, stone-free rate was 90.6% at the first procedure and 100% after the additional procedure. The final stone-free rates and operative times were similar in both groups. Conclusions: RIRS should be an effective treatment alternative to PNL in lower pole stones larger than 2 cm, especially in selected patients Daha fazlası Daha az

To assess the impact of a diagnosis of bladder cancer on smoking behavior and to analyze the role of the physician in smoking cessation. Nonmuscle-invasive bladder cancer patients completed a phone survey of their smoking habits. They were asked about smoking behavior before and after the diagnosis of cancer and whether they had been informed by their physician about the relation between smoking and bladder cancer. Two hundred-twelve patients responded to the survey. The mean age was 60.03±6.36 years. Ninety-three of the 135 current smokers (68.9%) were advised to quit smoking, whereas nine of 20 nonsmokers (45%) were not commented . . .about the future risks of smoking. The results showed that 13% of the current smokers and 35% of the current nonsmokers were not warned about the relation of bladder cancer with smoking. Statistical significance was not seen in terms of sex, disease stage, and tumor grade at diagnosis. The relation between smoking and bladder cancer has been well established. However, some patients are not informed to quit smoking by their physicians. © 2015, TIP ARASTIRMALARI DERNEGI. All rights reserved Daha fazlası Daha az

The aim of the study was to evaluate the efficacy and safety of bilateral single- -session retrograde intrarenal surgery in the treatment of bilateral renal stones. Materials and Methods: From December 2008 to February 2012, 42 patients who had undergone bilateral single-session retrograde intrarenal surgery (RIRS) and laser lithotripsy were included in the study. The procedures were performed in the lithotomy position on an endoscopy table under general anesthesia, beginning on the side in which the stone size was smaller. Plain abdominal radiography, intravenous urograms (IVU), renal ultrasonography (USG) and/or non-contrast tomog . . .raphy (CT) scans were conducted for all patients. The success rate was defined as patients who were stone-free or only had residual fragment less than 4 mm. A total of 42 patients (28 male, 14 female) with a mean age 39.2 ± 14.2 were included in the present study. The mean stone size was 24.09 ± 6.37 mm with a mean operative time of 51.08 ± 15.22 minutes. The stone-free rates (SFR) were 92.8% and 97.6% after the first and second procedures, respectively. The average hospital stay was 1.37 ± 0.72 days. In two patients (4.7%), minor complications (Clavien I or II) were observed, whereas no major complications (Clavien III-V) or blood transfusions were noted in the studied group. Bilateral single-session RIRS and laser lithotripsy can be performed safely and effectively with a high success rate and low complication rate in patients with bilateral renal stones Daha fazlası Daha az

Background: Lower urinary tract (LUT) discomfort is a common complaint after transurethral resection of the prostate (TURP), and it may lead to agitation and restlessnes. We have evaluated the efficacy of morphine for preventing TURP-related LUT discomfort symptoms. Methods: This was a prospective randomised study including 60 patients (American Society of Anesthesiologists class I and II) who were scheduled to undergo TURP. The patients were divided into two equally sized groups (group M: morphine, group C: control). A standartized anesthesia method was used. Group M patients received morphine 0.04 mg/kg intravenous (iv) in 100 ml . . .of normal saline followed by an infusion of morphine for 24 h (0.01 mg/kg/h); group C patients received 100 ml normal saline 20 min before the expected extubation time, followed by a normal saline infusion which looked identical to that of the morphine infusion. The incidences and severity of LUT discomfort, postoperative pain, sedation level, postoperative nausea and vomiting (PONV) and respiratory depression were recorded at 0, 1, 2, 6, 12 and 24 h postoperatively. Results: The incidence of LUT discomfort was lower in group M patients at all time points during the study (p < 0.05) except for 2 h postoperatively, and the severity of LUT discomfort was also lower this group at 0, 12 and 24 h postoperatively (p = 0.001, p = 0.04 and p = 0.02, respectively). Pain (numeric rating scale) scores were lower in group M patients at 0 (p = 0.003) and 6 h (p < 0.001). The need for rescue analgesic was lower in group M patients (19 patients in group C, 10 patients in group M; p = 0.04). The incidence of PONV was higher in group M patients (p = 0.03). The incidence of pruritus, respiratory depression and over-sedation were similar among the groups. Conclusion: Based on these results, we conclude that morphine effectively reduces LUT discomfort after TURP at a cost of postoperative nausea and vomiting. © 2013 Japanese Society of Anesthesiologists Daha fazlası Daha az
