Role of ejaculation in the treatment of chronic non-bacterial prostatitis

Background: Chronic non‐bacterial prostatitis (NBP) is the most common prostatitis syndrome. Prevention and cure are not possible because the cause of NBP is unknown. However, patients may benefit from supportive measures. The impact of the frequency of ejaculation alone on the course of NBP was evaluated in the present study.

Treatment of Retrocaval Ureter by Pure Laparoscopic Pyelopyelostomy: Experience on 4 Patients

OBJECTIVES To present our experience and the feasibility of pure laparoscopic pyelopyelostomy for treatment of retrocaval ureter (RCU). METHODS RCU was detected in 4 male (ages: 4, 16, 36, 48) patients, with complaints of flank pain. In all the patients, Type 1 RCU was present and the right ureter was involved. All patients underwent intraoperative retrograde pyelography before laparoscopy. The patients were operated upon using the transperitoneal approach in the lateral decubitis position, with two 10 mm and two 5 mm ports. After the ureter was released from the superior and inferior parts of the inferior vena cava, the dilated renal pelvis was transected and the ureter was brought in an anterolateral position to the vena cava. After the completion of the posterior wall anastomosis of pyelopyelostomy with 4-0 polyglactin sutures in a continuous manner, a double-J-stent was placed and the anterior wall was anastomosed in a watertight manner. A drain was placed in the operative area and the operation was completed. RESULTS Mean operation time was 210 minutes. No intraoperative complications occurred. In one patient, antegrade double-J-stent placement failed, and the stent was therefore placed in the retrograde way without any complications. Postsurgery, the urethral catheter was removed on the first day, and the drain on the second. All patients were discharged 48 hours after surgery. The third month postoperative follow-up confirmed that the anastomoses were patent and patients were symptom-free. CONCLUSIONS Pure laparoscopic pyelopyelostomy seems technically feasible and reliable for RCU treatment. Our experience showed that laparoscopy should be the standard treatment option for such patients.

Association of vitamin D receptor gene Taq I polymorphism with recurrent urolithiasis in children

Objective:  Urolithiasis has a strong familial component. However, to date, no specific genetic abnormality has been identified. It has been reported that allelic variation in the vitamin D receptor (VDR) gene may affect calcium absorption and excretion. Urolithiasis is a multifactorial disease in which both genetic and environmental factors have an effect on onset and severity of disease. In the present study, the role of Taq I polymorphism of vitamin D receptor gene in urolithiasis was studied.

Public awareness of testicular cancer and self-examination in Turkey: A multicenter study of Turkish Urooncology Society

BACKGROUND Testicular self-examination is the easiest and cheapest way to scan testicular cancer. However, the public awareness about testicular self-examination is very low. We aimed to investigate the public awareness of Turkish people about testicular cancer and testicular self-examination. METHODS We performed a survey consisting of 10 questions concerning testicular cancer and testicular self-examination in 799 students in the first year of 12 different medical schools. Aiming for a common method of data collection, the questionnaires were administered to the students during a class just before the lesson started. The whole data from all of the centers were pooled in a common data-base file. RESULTS Eighty-nine (11.1%) of the participants reported that they had knowledge about testicular cancer, but only 11 (1.4%) of them answered all the questions about testicular cancer correctly. Eight (1%) of the participants reported that they had been performing testicular self-examination routinely once a month. Four (0.5%) of them were both well informed about testicular cancer and had been performing testicular self-examination once a month as suggested. CONCLUSION The present study showed that awareness on testicular cancer and testicular self-examination is very low and suggests a need for efforts in Turkey to increase public awareness and education.

Small cell carcinoma of the urinary bladder. A clinicopathologic study of five cases

Aims and Background Small cell carcinoma of the bladder (SCCB) is a rare entity characterized clinically by an aggressive behavior with a high incidence of systemic metastases. We report the clinicopathologic findings of five cases. Methods We reviewed five consecutive patients with SCCB treated at our institute. In each case the following clinical data were recorded: age, sex, presenting symptoms, endoscopically determined location of the tumor, clinical staging, node involvement (if any), site of metastases (if any), treatment, follow-up and outcome. Results There were four male and one female patients, age range 42 to 68 years, mean 57.6 years. The clinical presentation was not different from conventional transitional cell carcinoma, with hematuria being the most frequent complaint (four cases). Microscopic examination revealed oat cells in three cases and an intermediate variant in one. At the time of diagnosis the tumors were staged as T3bN2M0, T2N2M0, T4N0M0, T3aN0M0, and T2N0M0. Primary therapy consisted of radical cystectomy alone (one case), transurethral resection (TUR) alone (one case), TUR with chemotherapy (two cases), or TUR with chemotherapy and radiotherapy (one case). Four patients died of progressive disease, with survival from the time of diagnosis ranging from 7 to 16 months (mean, 12.2 months). One patient died of myocardial infarction (unrelated to the primary disease) one month after diagnosis. Conclusion Our study indicates that primary small cell carcinoma of the urinary bladder is as aggressive as its pulmonary counterpart and the overall prognosis of this tumor is very poor.

RENAL CELL CARCINOMA WITH SOLITARY SYNCHRONOUS PANCREATICODUODENAL AND METACHRONOUS PERIPROSTATIC METASTASES : REPORT OF A CASE

We report herein the case of a patient who underwent successful resection of a solitary metachronous periprostatic metastasis 12 months after undergoing a right radical nephrectomy with pylorus-preserving pancreatico-duodenectomy for renal cell carcinoma (RCC) with a synchronous pancreaticoduodenal metastasis. At present the patient is free of any signs of recurrence 12 months after removal of the metachronous mass in the periprostate. This case report supports the opinion that an aggressive surgical approach is appropriate for RCC metastasis.

Percutaneous Suprapubic Transvesical Route: A New and Comfortable Method of Intraprostatic Injection

To assess the efficacy and safety of the percutaneous suprapubic transvesical route (STR) for intraprostatic antibiotic injections and compare it with the transperineal route (TPR), a total of 37 patients suffering from chronic bacterial prostatitis, resistant even to treatment with fluoroquinolones, were randomized to intraprostatic amikacin injections using either STR (n = 19) or TPR (n = 18). Follow-ups were done at weeks 4, 12, 24 and 52. Patients found to have failures at the first follow-up were given an additional injection using the initial route. At the 24th week, 15 patients from both groups were given another injection using the alternative route and were asked to report any subsequent voiding difficulties and compare the discomfort and pain experienced. At the end of 52 weeks, bacteriological cure rates did not differ significantly (44.4 vs. 47.3%). Overall improvement rates in the severity of symptoms and signs were similiar. Considerable difficulty in directing the needle to the prostate due to an excessive amount of subcutaneous fat was experienced, and more than 1 skin puncture was necessary in 5 of the STR group, whereas in the TPR group 7 patients with external hemorrhoids and 1 patient with a rectal fissure had prominent discomfort and pain during the transperineal procedures. Complications such as dysuria or hemospermia were encountered infrequently in both groups, but hematuria was observed more frequently in the STR group (85 vs. 54%). Less discomfort (p < 0.01) and pain (p < 0.01) were reported during access to the prostate by STR, but pain during the injection of the drug did not differ significantly. In conclusion, the percutaneous STR may well be used efficiently and comfortably as an alternative method to TPR when intraprostatic injections are needed in a limited number of cases such as those with a known hypersensitivity to fluoroquinolones or with a history of failure despite long-term systemic treatment with these agents.

Cardiac and caval invasion of left adrenocortical carcinoma.

Adrenocortical carcinoma (ACC) is a rare and highly malignant neoplasm. We present the case of a 51-year-old male patient with a left-sided ACC admitted to hospital with ipsilateral flank pain, weight loss, difficulty in breathing, abdominal discomfort and swelling and bilateral leg edema. Thoracoabdominal computed tomography revealed a huge adrenal mass with obvious tumor thrombus involvement of the inferior vena cava and right atrium. This is the first report describing caval and opposite side renal vein invasion of a left-sided ACC treated with grafting of the vessels. Histopathological examination of the tumors confirmed the diagnosis of ACC. Postoperative recovery was uneventful. The patient received an adrenolytic agent, mitotane, postoperatively and is alive with no evidence of recurrence after 2 years of follow-up.

Pneumatic Lithotriptor - A Useful Tool for Challenging Renal Stone Surgery

Open surgical measures may be undertaken in the treatment of some complex calculi and manoeuvres such as extended pyelolithotomy or nephrolithotomy may be necessary. In an attempt to improve surgical results with less morbidity and maximum ease, we used the Swiss Lithoclast to disintegrate large stones presenting as hard cases.Five patients with renal pelvic stones associated with calyceal stones in two and two further cases with staghorn stones were treated surgically using the pneumatic lithotriptor probe with less dissection and without nephrotomy. Only one of the patients with staghorn stones had residual fragments which were then treated with ESWL.We believe that when open surgical treatment is considered in hard cases, especially in those with small renal pelvises, the best results may be achieved with minimum surgical intervention if it is combined with pneumatic lithotripsy.

Coincidental adrenal ganglioneuroma - a case presenting with enuresis nocturna

A 9-year-old boy presenting with primary enuresis nocturna was discovered to harbour a large left adrenal mass which produced no hormonal abnormalities. He was undergone an exploration and the mass was removed completely. It was found to be an adrenal ganglioneuroma weighing 240 g. Though no cause-and-effect relationship is established, the case no long suffered from enuresis soon after surgery and free of recurrence after 5 years.
