Deleterious effects of selective serotonin reuptake inhibitor treatment on semen parameters in patients with lifelong premature ejaculation.

Premature ejaculation (PE), the most common sexual dysfunctions in men, is characterized by loss or absence of ejaculatory control. PE can be classified as either a lifelong or acquired condition. Although the prevalence of lifelong PE is rather low in the general male population, recent studies demonstrated that the patients who seek treatment for their rapid ejaculation mostly report lifelong PE. Although no drug for PE has been approved by regulatory bodies, chronic selective serotonin reuptake inhibitors (SSRIs) proved to be effective in treating lifelong PE. Despite the rising use and known effects of antidepressants on ejaculation, only a few reports have evaluated the impact of these drugs on the male fertility. Thus, the aim of this review is to evaluate the efficacy and adverse effects of SSRIs on semen parameters of patients with lifelong PE as well as to assess the safety of this treatment among sexually active couples who desire to have a child.

Robotic-assisted laparoscopic nephroureterectomy and bladder cuff excision.

BACKGROUND AND OBJECTIVES: Our aim was to show that bladder cuff excision and distal ureterectomy can be safely performed by using the LigaSure device during robotic-assisted laparoscopic nephroureterectomy. METHODS: A 60-year-old man presented with gross hematuria. He was diagnosed with upper urinary tract transitional cell carcinoma (TCC) on the left side and was scheduled for robot-assisted laparoscopic surgery. Without changing the patient's position, sealing with the LigaSure atlas for bladder cuff excision and distal ureterectomy was performed. RESULTS: The operating time was 140 minutes from the initial incision to skin closure of all incisions. The estimated blood loss during the surgery was 120 mL. There were no intraoperative or postoperative complications. The Foley drain was removed on day 3 after normal cystographic findings, and the patient was discharged from the hospital on the fourth postoperative day. CONCLUSION: Robot-assisted nephroureterectomy with distal ureterectomy in the same position using a LigaSure device is a safe alternative for upper tract transitional cell carcinoma.

The actual incidence of papaverine-induced priapism in patients with erectile dysfunction following penile colour Doppler ultrasonography.

Penile color Doppler sonography is a valuable method for evaluating erectile dysfunction. However, there are some concerns about the safety of this method due to the intracorporeal pharmacological injection, which may cause priapism as a complication, resulting in penile fibrosis. To evaluate the actual incidence of papaverine-induced priapism in patients with erectile dysfunction (ED) who underwent penile colour Doppler sonography and to determine the safety of this diagnostic tool, a retrospective study was conducted using the database of our institution. A total of 672 men with ED underwent penile color Doppler ultrasonography with the intracorporeal injection of 60 mg papaverine hydrochloride. The patient characteristics of priapism cases were retrospectively evaluated. Priapism in 18 of the 672 patients (2.68%) was successfully treated with blood aspiration, irrigation and injection of an alpha-agonist medication, when needed. Patients with priapism were younger compared with those without priapism; mean age 45 +/- 12.51 (20-68) versus 50.93 +/- 12.04 (17-78) (P < 0.001). Penile Doppler ultrasound is a safe procedure in evaluating erectile dysfunction. The incidence of priapism, which is the most important complication of this procedure, is low and can be managed successfully with conservative approaches.

Penile blood cyclic guanosin monophosphate level is associated with penile Doppler ultrasound findings.

The aim of this study was to look into a molecule in penile blood sample that shows correlation with the tumescence grade and/or penile Doppler ultrasound findings. Patients admitted to urology outpatient clinic with the complaint of erectile dysfunction between November 2006 and April 2007 were evaluated. Patients with the history of phosphodiesterase inhibitor usage or genital trauma, genital abnormalities, Peyronie's disease, endocrinopathies, cardiovascular diseases and major psychiatric or neurological disorders were excluded. Those patients were later evaluated with a penile Doppler ultrasound, 10-20 min after intracavernosal injection of 60 mg of papaverine hydrochloride. Tumescence grade, peak-systolic velocity (PSV), end-diastolic velocity (EDV) and resistive index (RI) were recorded. Blood samples were drawn from penis and the levels of calcium, myeloperoxidase, malondialdehyde, nitrite, nitrate, vasoactive intestinal peptide and cyclic guanosin monophosphate (cGMP) and the activity of superoxide dismutase were measured. A total of 46 patients with erectile dysfunction were included. The median age of the patients was 49.3+/-10.2 (range 24-67). We could not find any significant correlation between penile Doppler ultrasound parameters and any of penile blood measurements except cGMP that demonstrated a significant negative correlation with PSV (rho=-0.533, P=0.001) and RI (rho=-0.468, P=0.005). However, a positive correlation between cGMP and EDV was detected (rho=0.322, P=0.059). Mean cGMP levels were 3.347+/-0.694 pmol ml(-1) (2.295-4.685), 3.193+/-0.669 pmol ml(-1) (2.165-4.094) and 2.742+/-0.690 pmol ml(-1) (1.290-4.011) in grades 2, 3 and 4 tumescence groups, respectively, and the difference among mean cGMP levels of these groups were statistically significant (P=0.027). As a conclusion, penile blood cGMP level showed a significant negative correlation with mean PSV, RI values and tumescence grade, whereas there was a positive but insignificant correlation between cGMP and mean EDV value.

Turkish validation of the premature ejaculation diagnostic tool and its association with intravaginal ejaculatory latency time.

There are uncertain issues on the diagnostic methods of premature ejaculation (PE). The premature ejaculation diagnostic tool (PEDT) was developed to systematically apply the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria in diagnosing PE and the aim of this study is to carry out the Turkish validation of the PEDT and to evaluate its association with intravaginal ejaculatory latency time (IELT). A total of 94 patients with a self-reported complaint of PE and 88 men without PE were enrolled into the study and requested to complete the nine-item PEDT, which was translated into Turkish. The patients were also requested to measure IELT. All participants were requested to come for a second visit to assess the PEDT's retest reliability; data from 78 men in the PE group and 69 men in the control group were collected. The IELT data of 35 patients were also recorded. The mean age of the PE group and the control group were 39.4+/-9.7 (24-65) and 30.1+/-5.7 (20-56), respectively, (P=0.068). Among the patients in the PE group, 24 (68.5%) reported life-long PE, whereas 11 (31.5%) reported acquired PE. The geometric mean IELT of the PE group was 59.7+/-46.2 (6.5-197.7) s. The number of men reporting IELTs of <1, 1-<2 and >2 min were 20 (57.1%), 11 (31.5) and 4 (11.4%), respectively. The factor analysis assessment showed that the five-item combination (questions 1, 2, 3, 4 and 8) explained 74.4% of the variance, there were no other combinations that explained the variance more effectively. Cronbach's alpha score of five-item combination was calculated as 0.77, showing adequate internal consistency. The overall Cronbach's alpha score did not increase if any item combination was deleted. The test-retest correlation coefficients of each item were higher than 0.80 and the correlation coefficient of the total score was 0.90. The PEDT and IELT showed an adequate correlation (rho=0.44). As a conclusion, the validated five-item Turkish version of PEDT is a reliable questionnaire to screen PE among Turkish patients. Its significant association with IELT supports the fact that PEDT may be of benefit for the diagnosis of PE and measuring the response to treatment. In addition, PEDT seems to be more applicable than measuring IELT in our population, for the assessment of PE.
