Abstract Although prostatic calculi are relatively common, the etiology of these stones is not clear. We report a case with multiple prostatic calculi causing urinary obstruction and a concomitant bladder stone. We treated these stones endoscopically. We found a lot of different sized stones endoscopically, some protruding into the urethra, some filling different cavities on the prostate. So these cavities suggest prostatic calculi may occur related to intraprostatic reflux in the congenital or acquired diverticulum of the prostatic tissue. In addition, the stone composition of the bladder and prostatic stones was the same. All of these results show that the origin of bladder and prostatic stones can be the same. This case also supports a theory of intraprostatic reflux and urine stasis.

Transitional cell carcinoma (TCC) of the bladder is the seventh most frequent cancer of women. The possible mechanisms of local tumor recurrence are seeding and multicentricity. Distant metastases are most frequently as a result of vascular or lymphatic spread and to a lesser extent by seeding of the tumor cells with urine or transurethral instrumentation. We report a clitoral metastasis of a TCC of the bladder, which is a very unexpected and extremely rare site for metatstasis and discuss whether the possible mechanism is vascular spreading or direct seeding. To our knowledge this is the third case in the literature.

Imaging the urinary tract in children has been mainly based on ultrasound (US) and intravenous pyelography (IVP), but these imaging modalities rarely show ectopic insertion of the ureter and the condition is often under diagnosed due to unusual clinical presentations. Recently newer magnetic resonance urography sequences have been developed that provide better delineation of the urinary tract. We report a 3-year-old girl presenting continuous dribbling of urine in which magnetic resonance urography revealed ectopic vaginal insertion of the ureter.

PURPOSE To assess whether Foley catheterization of the rectum after transrectal ultrasound (TRUS)-guided prostate biopsy decreases complication rates. MATERIALS AND METHODS Between June 2000 and September 2006, 275 consecutive patients were evaluated after undergoing TRUS-guided prostate biopsy. All procedures were performed on an outpatient basis. Patients were divided into two groups. In the first group (n = 134), a Foley catheter was inserted into the rectum and inflated to 50 cm(3) after TRUS-guided biopsy. In the second group (n = 141), catheterization was performed without balloon placement. Rectal bleeding, hematuria, hematospermia, infection, and acute urinary retention rates were compared between groups. RESULTS The mean ages of the patients were 63.3 years +/- 5.6 and 62.1 years +/- 7.2 years in the Foley catheter group and control group, respectively (P = .112). Hematuria, hematospermia, infection, and rectal bleeding occurred in 31 (23.1%), 30 (22.4), nine (6.7%), and two patients (1.5%), respectively, in the Foley catheter group; and in 36 (25.5%), 36 (25.5%), 11 (7.8%), and 25 patients (17.7%), respectively, in the control group. The incidences of infection, hematuria, and hematospermia were not significantly different between groups (P > .05). In contrast, the rectal bleeding rate was significantly lower in the Foley catheter group (1.5%) than in the control group (17.7%; P = .001). CONCLUSIONS Although it has no effect on other complications, TRUS-guided prostate biopsy with rectal Foley catheterization is a useful, practical method to decrease or prevent rectal bleeding.

AIM To evaluate the possible relationship between varicocele and chronic constipation. METHODS Between April 2009 and May 2010, a total of 135 patients with varicocele or constipation and 120 healthy controls were evaluated. Patients were divided into two groups. In both groups detailed medical history was taken and all patients were examined physically by the same urologist and gastroenterologist. All of them were evaluated by color Doppler ultrasonography. All patients with constipation, except for the healthy controls of the second group, underwent a colonoscopy to identify the etiology of the constipation. In the first group, we determined the rate of chronic constipation in patients with varicocele and in the second group, the rate of varicocele in patients with chronic constipation. In both groups, the rate of the disease was compared with age-matched healthy controls. In the second group, the results of colonoscopies in the patients with chronic constipations were also evaluated. RESULTS In the first group, mean age of the study and control groups were 22.9 ± 4.47 and 21.8 ± 7.21 years, respectively (P < 0.05). In the second group, mean age of the study and control groups were 52.8 ± 33.3 and 51.7 ± 54.3 years, respectively (P < 0.05). In the first group, chronic constipation was observed in 8 of the 69 patients with varicocele (11.6%) and 3 out of 60 in healthy controls (5%), respectively. In this regard, there was no statistical significance between varicocele patients and the healthy control (P = 0.37). In the second group, varicocele was observed in 16 of the 66 patients with chronic constipation (24.24%) and 12 out of 60 in healthy controls (20%) respectively. Similarly, there was no statistical significance between chronic constipation and healthy controls (P = 0.72). Internal/external hemorrhoids were detected in 4 of the 16 patients with chronic constipation and varicocele, in the second group. In the remaining 50 patients with chronic constipation 9 had internal/external hemorrhoids. In this regard, there was no statistical significance between chronic constipation and healthy controls (P = 0.80). CONCLUSION Chronic constipation may not be a major predictive factor for the development of varicocele, but it may be a facilitator factor for varicocele.

OBJECTIVE Von Willebrand factor (vWF) is a mediator that increases endotoxemic medium like in cirrhosis. In this study we evaluated the association of serum VWF antigen (Ag) level with the stage of cirrhosis (according to Child-Pugh classification). MATERIALS AND METHODS We included 82 cirrhotic patients (Female/Male (F/M): 26/56) and 86 healthy subjects (F/M: 44/42) in the study. Ages of the both groups of patients were not different (P= 0.095). We excluded possible other reasons that may cause VWF level increase. Diagnosis of cirrhosis was made on the basis of biopsy in 7 patients and with clinical and laboratory parameters in 75 patients. VWF Ag level was determined by immunoturbidimetric test. The stage of cirrhosis was defined with Child-Pugh classification. Data were analysed by using Statistical Package for the Social Sciences (SPSS) 10.0 software program. RESULTS VWF Ag level was significantly higher in cirrhotic patients compared to control group (220±90 and 87±38, P<0.001, respectively). We observed significant increase of VWF Ag level with the increasing stages of cirrhosis according to Child-Pugh score (VWF Ag level for Child A-B-C 156.4±54/215±45/284.8±93, respectively; P values for Child A-B/A-C/B-C; <0.001/<0.001/0.006, respectively). CONCLUSION Serum VWF Ag level increases in cirrhotic patients and this is more pronounced with higher stages of cirrhosis.

Introduction: In this study, our aim was to evaluate the effectiveness of the mucosal flap barrier (MFB) upon the incompetent ureteral orifice of an experimentally produced rabbit reflux model. The rabbit reflux model was done in the first stage of the study. This method is a new and original procedure which is different from Bischoff’s and Witherington’s osteoplasty techniques. Materials and Methods: We performed the mucosal flap procedure in eight 2–2.5 kg male New Zealand rabbits with experimentally produced refluxing ureters. The first stage of our study was to create refluxing ureters. Due to the upward and inward ‘J’ fishhook course of the intravesical ureter of rabbits, we performed two deep 12- and 4-o’clock incisions by suturing the edges of the intravesical ureter apart with catgut sutures. Additionally, to stop the tilting action of the trigonum during micturition, we performed two parallel incisions between the ureteral meatus. These parallel incisions were the authors’ modifications for the rabbit reflux model and which gives long-lasting reflux for the rabbit. We checked the reflux at the end of the 3rd month and performed our new MFB antireflux procedure. This mucosal flap made a cover on the incompetent ureteral orifice. This technique is completely different from the osteoplasty techniques described by Bischoff and Witherington. Results: Four months after the MFB application, we performed intravenous urography, cystometry and cinefluorography. There was no obstruction or reflux. Two rabbits were sacrificed at the 4th month. Both flaps were fully intact without any fixation at the medial side causing obstruction. At present, 3 rabbits are still alive. We did cinefluorography and cystometry at the 15th month and there was no obstruction or reflux. We are trying to keep them alive till the end of their natural lifespan. Conclusions: During the formation of the rabbit reflux model, we observed that spontaneous reflux even at high intravesical pressures did not have high percentages as previously mentioned in the literature. But it is possible and enough to produce an experimental reflux model by using meatotomy and interureteric incisions. Moreover, in rabbits with vesicoureteral regurgitation produced by ureteral meatotomy and interureteral incisions, reflux can be eliminated the MFB procedure. This method is an easy procedure for small bladders or dilated ureters after any kind of open reimplantation applications and it could be used by pneumovesical applications in the future.
