Association between male accesory gland infections and prostate cancer in Turkish men: A case-control study.

It is well known that chronic inflammation contributes to several forms of human cancer. Although several studies have investigated the association between prostatitis and prostate cancer, there is a lack of specifically designed study about male accessory gland infections (MAGI) and prostate cancer co-occurrence. We aimed to investigate this association with a case-control study in Turkish men. A total of 155 patients were enrolled to the study. After the pathological examination of the transrectal ultrasound-guided prostate biopsy specimens, patients were divided the two groups as control and prostate cancer and the presence of MAGI was determined. Of 155 patients, 145 met inclusion criteria. In the prostate cancer group, MAGI diagnose was determined in 18 of 31 patients (58.06%), while it was determined in 25 of 114 (21.93%) patients in the control group (p = .001). A significant correlation between MAGI and pathological Gleason score also revealed (p = .0001). We demonstrated that men with MAGI have increased risk for the development of prostate cancer. Moreover, in this population, most of the prostate cancers tend to be clinically significant or high grade.

Retrograde intrarenal surgery in the management of pediatric cystine stones.

OBJECTIVE: To investigate the efficacy and safety of retrograde intrarenal surgery (RIRS) in the treatment of pediatric cystine stones. STUDY DESIGN: Data of the pediatric patients who underwent RIRS for kidney stones were retrospectively evaluated. A total of 14 children with cystine stones managed with RIRS were identified. In addition to the patient demographics and stone characteristics, all retrospectively obtained operative data were evaluated and discussed in detail, with an emphasis on the success and complication rates. RESULTS: Mean age of the 14 cases was 10.9 ± 2.2 years (range: 7-15). Mean stone size was 13.6 ± 2.4 mm (range: 10-18) (Summary table). Of these stones, four were located in the renal pelvis, three were in the lower, three were in the middle and the remaining four were located in upper calyx. Ureteral access sheath was used in 12 (85.7%) patients. The double-J ureteral stent was placed pre-operatively in one case and was inserted postoperatively in 12 cases. Mean operation time was 38.2 ± 7.2 min (range: 30-50). Complications were observed in two cases: mild ureteral laceration in the first and fever on the second postoperative day in the second patient. All of the patients were stone free on sonographic evaluation at the 4-week follow-up evaluation. Although potassium citrate treatment was initiated in 11 patients, tiopronin treatment was initiated in four patients for recurrence prophylaxis during long-term follow-up. During a mean follow-up period of 25.7 ± 5.2 months, stone recurrence was noted in one patient. DISCUSSION: Treatment of patients with cystine stones is challenging, due to high risk of rapid recurrence in the presence of residual fragments. Besides allowing complete stone clearance in all cases in the current series, RIRS is a highly reproducible method that can be safely performed, even in recurrences. The major limitations of the current study were low number of patients and short follow-up period. CONCLUSION: The results clearly indicated that RIRS is a safe treatment modality in the management of pediatric cystine stones.

Mucosal cuff length to penile length ratio may affect the risk of premature ejaculation in circumcised males.

Data regarding the relation between premature ejaculation (PE) and post-circumcision mucosal cuff length are controversial. The aim of this study is to analyze the relation between post-circumcision mucosal cuff length/penile length ratio (MCR) and PE. After exclusion of patients with erectile dysfunction, penile deformity, history of penile surgery and severe lower urinary tract symptoms, 49 circumcised men with PE were included. The control group is constituted of 50 healthy volunteers with normal ejaculatory function. Self-estimated intravaginal ejaculation latency time (IELT) and premature ejaculation profile (PEP) measures of all subjects were recorded, and the MCRs of patients and controls were compared. The mean age of PE patients and controls was 35.82 ± 7.73 (range 23-54) and 38.78 ± 13.42 (range 19-71) years, respectively (P=0.183). Although mucosal cuff length was not associated with either self-estimated IELT (r=-0.185, P=0.067) or PEP (r=-0.098, P=0.336), there was a negative correlation between MCR and self-estimated IELT (r=-0.205, P=0.0001) and PEP measures (r=-0.308, P=0.002). The length of the mucosal cuff after circumcision may have an impact on ejaculatory function. Surgeons should avoid leaving excessive amount of mucosa during circumcision.

Priapism in the newborn: management and review of literature.

Priapism is a pathological condition of a penile erection that persists beyond or is unrelated to sexual stimulation. Priapism is broadly classified into two types: (i) ischaemic priapism (veno-occlusive) (low-flow), (ii) nonischaemic priapism (arterial) (high-flow). We report the case of a newborn presenting with priapism on the first day of life and also review published data on the management and follow-up of this condition.

Age-specific PSA reference ranges in a group of non-urologic patients.

Age-specific serum PSA reference ranges have recently been proposed to be more sensitive in young and more specific in elder patients. However, some conflicting results have been reported from different centers. In order to establish age-specific PSA reference ranges for our country, we measured the serum PSA levels of 400 healthy men over 40, between February 1995 and June 1996. Our study population consisted of men who had either PSA values lower than 4.0 ng/ml and normal digital rectal examination or negative prostatic biopsies taken for any reason. IMX assay was used for PSA determination in all patients. Mean PSA values and standard deviations for each age group were: 1.7+/-1.1 ng/ml for 40-49 years (n = 28), 2.0+/-1.2 ng/ml for 50-59 years (n = 110), 2.9+/-1.7 ng/ml for 60-69 years (n = 158) and 3.5+/-2.0 ng/ml for 70-79 years (n = 104). We conclude that further studies of larger series will lead us to standardize age-specific reference ranges in our country and, accordingly, we will be able to select the candidates for prostate biopsy more adequately.

A distal ureteral fibrous polyp and the role of ureteroscopic resection in its management.

Fibroepithelial polyps of the ureter are rare benign mesodermal tumors that occur most often in the proximal ureter. We describe a case of a fibrous polyp in the distal ureter and discuss the role of ureteroscopic resection in the management of this condition.
