Bilateral renal choriocarcinoma in a postmenopausal woman.

Choriocarcinoma is the most malignant tumor of gestational trophoblastic neoplasia. It grows rapidly and metastasizes to the lung, liver, and less frequently, the brain. Metastases to the kidney are rare in the literature, and bilateral involvement is even more scarce.

Pseudosarcomatous fibromyxoid tumor of the prostate.

We present the case of a 61-year-old patient who was evaluated for benign infravesical obstruction due to a pseudosarcomatous fibromyxoid tumor of the prostate. This entity is rare and difficult to distinguish from a malignant lesion. A discussion of the pathological features and a review of the literature are given.

Testicular polyarteritis nodosa mimicking testicular neoplasm.

Polyarteritis nodosa (PAN) presents mostly as a systemic disease characterized by necrotizing vasculitis affecting small- and medium-sized arteries. Rarely, the inflammatory process is isolated and involves a single organ without systemic manifestations. We described the case of a 57-year-old patient with isolated testicular PAN who presented with a testicular mass mimicking a primary testicular tumor.

The randomized comparison of two different endoscopic techniques in the management of large bladder stones: transurethral use of nephroscope or cystoscope?

Purpose: Endoscopic treatment of large bladder stones via cystoscope is still bothersome, and open cystolithotomy is the preferred method in many centers. To gain more insight into the endoscopic bladder stone management, we aimed to compare the transurethral use of nephroscope and cystoscope randomly.

Patients And Methods: Forty-three male patients with bladder stones were randomized into two groups, to perform nephroscopic (group 1, n = 22) and cystoscopic (group 2, n = 21) stone fragmentation procedures transurethrally.

Alteration in contractile responses in human detrusor smooth muscle from obstructed bladders with overactivity.

Introduction: In this study, we aimed to evaluate changes in contractile responses under in vitro conditions in detrusor overactivity (DO) in patients with bladder outflow obstruction (BOO).

Materials And Methods: Detrusor strips obtained during open prostatectomy procedure from 16 patients with BOO related to benign prostate hyperplasia were evaluated under in vitro conditions. Patients were assigned to two groups as patients with (DO) and without (no DO) DO.

Can pain during digital rectal examination help us to decide the necessity and the method of anesthesia for transrectal ultrasound guided prostate needle biopsy?

Objective: Transrectal ultrasound (TRUS) guided prostate biopsy is well tolerated by patients but the lack of an effective marker to predict pain prevents us from determining pre-procedurally which patient group needs local anesthesia for biopsy and probe pain. Thus in this study, we investigated predictor factors for prostate biopsy and probe insertion pain.

Materials And Methods: 71 patients who were undergoing prostate biopsy without anesthesia were included in the study retrospectively.

Are there predictive factors for the outcome of endoscopic treatment of grade III-V vesicoureteral reflux with dextranomer/hyaluronic acid in children?

Dextranomer/hyaluronic acid (Dx/HA) copolymer has been used widely for the treatment of vesicoureteral reflux (VUR) in children since 2001. However, the factors that influence the outcome of injection therapy with Dx/HA have remained unclear. In this study, we retrospectively evaluated the outcomes in 101 consecutive children to determine the cure and to identify the factors that can impact treatment outcomes of Dx/HA injection.

A large seminal vesicle cyst with contralateral renal agenesis.

Seminal vesicle cysts (SVC) are rather rare disorders. Our case is the first in literature where contralateral renal agenesis was seen together with SVC and surgically managed. We believe that the occurrence of these two coinciding abnormalities is incidental.

Comparison of transurethral resection and plasmakinetic transurethral resection applications with regard to fluid absorption amounts in benign prostate hyperplasia.

Introduction: We compare the absorption of irrigant fluid during gyrus plasmakinetic transurethral prostatectomy (PK-TURP) and transurethral resection of the prostate (TURP).

Patients And Methods: 42 patients with clinical benign prostatic hyperplasia were randomly assigned to undergo PK-TURP or TURP. In the PK-TURP group 0.

Do children with primary nocturnal enuresis have a retarded bone age? A cross-sectional study.

Objective: Nocturnal enuresis is a common pediatric problem, the etiology of which is unclear. In recent years, various studies have been published stating that children with nocturnal enuresis exhibit growth and skeletal maturation retardation.

Methods: In this cross-sectional study, we included 27 patients (16 boys, 11 girls) between the ages of 6 and 14 years who had presented with primary nocturnal enuresis (PNE) complaints.

Plasmakinetic prostate resection in the treatment of benign prostate hyperplasia: results of 1-year follow up.

Aim: In our randomized prospective study, we aimed to evaluate the efficiency of plasmakinetic resection of prostate (PKRP) by comparing the preoperative and postoperative results of the transurethral resection of prostate (TURP) and PKRP techniques which we administered in patients with benign prostate hyperplasia (BPH) in our clinic.

Methods: Of 57 patients for whom we thought an operative intervention was necessary, 30 cases in the first group had a TURP and 24 cases in the second group had a PKRP. International prostate symptom scores (I-PSS), uroflowmetry, measurement of residual urine amount and ultrasonography were performed for each patient both preoperatively and postoperatively (first month and first year).

Is the combination of superselective transcatheter autologous clot embolization and duplex sonography-guided compression therapy useful treatment option for the patients with high-flow priapism?

The aim of this study was to report feasibility, benefit and complications of superselective transcatheter autologous clot embolizations and duplex sonography-guided compression therapy in four patients with delayed post-traumatic high-flow priapism. Medical records of four consecutive patients diagnosed with delayed post-traumatic high-flow priapism (arterial priapism) were reviewed. High-flow priapism occurred mean 41.

Stoller afferent nerve stimulation in woman with therapy resistant over active bladder; a 1-year follow up.

Aim: In this prospective observational study, we investigated the efficacy of Stoller afferent nerve stimulation (SANS) in subjects with overactive bladder who failed anticholinergic treatment.

Methods: Thirty-five subjects with overactive bladder who failed therapy with oxybutynin participated in this study. Treatment (n = 35) was given once a week for 30 minutes for overall 10 weeks.

Effect of acute alcohol intake on prostate tissue and serum PSA-like protein levels in rats.

Objective: To investigate both the possible changes induced by acute alcohol intake on prostate tissue at the ultrastructural level and its effect on serum prostate-specific-antigen (PSA)-like protein levels in rats.

Materials And Methods: 44 male Wistar rats were included in the study in four separate groups; 7 treatment and 4 control animals were selected for each group. The treatment group received 40% ethanol (6 g/kg) while the control group was injected with the same dose of intraperitoneal isotonic saline.

Transurethral electrovaporization of the prostate: is it any better than standard transurethral prostatectomy? 5-year follow-up.

Background And Purpose: At present, transurethral resection of the prostate (TURP) is regarded as the most effective treatment for benign prostate hyperplasia (BPH). In the present randomized study, we compared TURP with transurethral electrovaporization of the prostate (TUVP).

Patients And Methods: A series of 77 BPH patients who underwent operation between 1996 and 2001 were included in the study, 40 who had TURP with a standard resection loop and 32 who had TUVP with a Spike loop.

Effect of intraurethral Mitomycin-C on healing and fibrosis in rats with experimentally induced urethral stricture.

Background: In the pathogenesis of urethral stricture, fibrosis is associated with an excessive collagen increase. After the recognition that topical application of Mitomycin-C (MMC) inhibits fibroblast proliferation and is effective in preventing scar formation, many studies have been carried out on this subject outside the scope of urology. The aim of the present study is to observe the intraurethral impact of the employment of low doses of MMC on scar formation and fibrosis in experimental rat model.
