Ninth commandment: 'Thou shalt not covet thy neighbor's wife!' Penetrating trauma to the corpora cavernosa caused by gunshot.

We describe a case of gunshot wound to the corpora cavernosa caused by a low-velocity bullet in a 43-year-old man. He volunteered that his lover's husband shot him with a handgun. The bullet had penetrated the right gluteal region with no exit wound causing a right corpus cavernosum lesion. A penile colour-duplex doppler ultrasonography did not reveal injuries of the cavernosal arteries or altered peak diastolic and systolic values. A three-dimensional computed tomography study corfirmed the presence of the bullet at the root of the right corpus cavernosum and allowed to identify the curvilinear ballistic trajectory, confirming a low-velocity penetrating bullet. The patient underwent exploratory surgery with removal of the bullet and primary repair of the identified unilateral albuginea rupture. The bullet, passing through clothing, probably slowed down causing less than expected harm. The follow-up visit after 2 months showed that the penile girth was not narrowed by such a repair. With a 2-year follow-up the patient has a normal penile ultrasound morphology and a normal sexual activity.

[Unilateral testicular cancer: incidence and effects of a contralateral testiculopathy on the sperm output].

AIM: The aim of this paper was to evaluate the incidence of a non-tumoral, contralateral primitive testiculopathy and its relative influence on sperm quality of patients with unilateral testicular cancer. METHODS: Twenty-four patients (mean age 26 years, range 19-38) with testicular germ cell cancer (seminomas, SEM, in 10 cases; nonseminomas, NSEM, in the remaining 14 patients) after orchiectomy and before radiotherapy or chemotherapy underwent semen analysis, physical examination and scrotal ultrasound of their survivor testis. RESULTS: Patients with SEM had sperm concentration, total sperm count and forward motility significantly higher than those found in patients with NSEM. Altogether, 5 out of 24 patients (2 SEM; 3 NSEM) (20.8%) showed azoospermia; 10 patients (41.7%) (3 SEM; 7 NSEM) had oligo-, astheno- and/or terato-zoospermia (OAT). The remaining 9 patients (37.5%) (5 SEM; 4 NSEM) showed normal sperm parameters. The testicular volume of the left over testis was reduced (<12 ml) in 4 out of 5 (80%) azoospermic patients, in 7 out of 10 patients (70%) of OAT patients, but in no patient (0%) with normozoospermia. A testicular biopsy performed on the survivor testis of 5 patients with azoospermia (4 of them had a reduced testicular volume) confirmed the primitive testiculopathy, showing a histological pattern of Sertoli cell syndrome only in 4 of them (80%) and maturation arrest in the other case (20%). CONCLUSIONS: Less (OAT) or more severe (azoospermia) sperm output impairment in patients with unilateral testicular cancer is associated with a coincidental, contralateral to unilateral testicular cancer, primitive testiculopathy expressed as reduced testicular volume and impairment spermatogenesis at the testicular biopsy.

Role of Ca 15-3 in patients with biochemically suspected prostate cancer and multiple negative ultrasound-guided prostate biopsies.

Ca 15-3 is an aspecific tumor marker characteristic of cancer proliferation. Elevated serum levels seem to be closely correlated with cancer progression in non-urological tumors. This study assessed the role of Ca 15-3 as an aspecific tumor marker in patients with borderline prostate-specific antigen (PSA) biochemically suspected of prostate cancer (PCa) and with multiple negative prostate biopsies. The study is based on prospective analysis of 103 patients: (a) 33 patients (group A) presented lower urinary tract symptoms secondary to BPH with normal serum PSA values, DRE and TRUS negative for suspected PCa; (b) 31 patients (group B) with histologically diagnosed PCa; (c) 39 patients (group C) with borderline serum PSA values, DRE and TRUS normal, two ultrasound (US)-guided random prostate biopsies negative for PCa. Ca 15-3 was determined in the entire study series by the IRMA method, using as range the values proposed for the investigated non-urological tumors (38 UI/l).Ca 15-3 was within normal range in all group A patients (control), while the values were elevated in 27/31 of group B patients (PCa) and in 11/39 of group C (PCa suspected) patients. A third biopsy was performed in all 39 group C patients with borderline PSA and it was PCa-positive in 13 patients (33.3%, subgroup C3). In this series Ca 15-3 was increased in 9 of 13 patients (subgroup C3alpha), while the remaining four patients (subgroup C3beta) presented values within the normal range. On 26 group C patients who were negative for PCa to third biopsy (subgroup C4), 24 patients had Ca 15-3 levels within normal range (subgroup C4alpha) with histologic findings of BPH in 23 cases and granulomatous chronic prostatitis in one case, while two patients (subgroup C4beta) had elevated Ca 15-3 concentrations associated with lymphoplasmacytic chronic prostatitis. We hypothesize that Ca 15-3, as a specific tumor marker, could be an interesting and inexpensive second step diagnostic tool for PCa in patients with borderline PSA and multiple negative prostate biopsies, as it could indicate whether a repeated biopsy should be performed in a short time, having excluded other concomitant tumors. However, further prospective studies will be necessary to confirm this hypothesis.

Efficacy and safety of fixed-dose oral sildenafil in the treatment of sexual dysfunction in depressed patients with idiopathic Parkinson's disease.

OBJECTIVE AND METHODS: The efficacy and safety of oral Sildenafil, a potent inhibitor of phosphodiesterase type 5, were evaluated in depressed men with idiopathic Parkinson's disease and erectile dysfunction. Thirty-three men were enrolled in a 4-month prospective, open-label, fixed-dose study, and received 50mg of Sildenafil in the home setting approximately 1 hour before sexual activity, not more than once daily. Efficacy was determined by responses to question 3 (ability to achieve an erection) and question 4 (ability to maintain an erection) of the 15-item International Index of Erectile Function (IIEF). Other measures of efficacy included the five sexual function domains of IIEF, a global efficacy question, the Beck Depression Inventory (BDI) and the Hamilton Depression Rating Scale-21 (HDRS-21). RESULTS: At the end of the study, improved erections were reported by 84.8% of patients. Sildenafil significantly increased patients' ability to achieve and maintain erections. Significant improvements were also observed in the IIEF domains for erectile function, orgasmic function, intercourse satisfaction and overall sexual satisfaction. BDI and HDRS scores improved from baseline to the end of the study. A clear improvement of depressive symptoms was observed in 75% of patients. Sildenafil was well tolerated in all the patients. CONCLUSIONS: Treatment with oral Sildenafil improves erectile function and, indirectly, depressive symptoms in patients with idiopathic Parkinson's disease stages 1-3, and is well tolerated.

[Mepartricine and prostatitis. Clinical experience and rationale for use].

BACKGROUND: The purpose of this study was to report our experience on the use of Mepartricine in the treatment of chronic and sub-acute prostatitis and to analyse, on the basis of the literature, the role of estrogens, the target of Mepartricine in the development and maintenance of prostatic inflammatory reactions. METHODS: In a retrospective study the data of 110 patients who presented with lower urinary tract symptoms suggestive of prostatitis, from January 1994 to February 1999 have been evaluated: 65 of this patients had an abacterial prostatitis, and 45 a bacterial prostatitis. The Mearers-Stamey test was used to localize inflammation and pathogens to prostate. The clinical symptoms presented were essentially pelvic and perineal pain and irritative and obstructive voiding symptoms. The treatment was based on antibiotic therapy indicated by the sensitivity to antibiotic assay. In abacterial prostatitis, in cases of Chlamidia, Mycoplasma and Ureaplasma positivity, the treatment was based on macrolides and tetracycline use. All the patients received Mepartricine by oral supply, 1 daily tablet (40 mg) for 60 days. RESULTS: After two months of treatment remarkable improvements in symptoms were obtained despite the persistent bacteriological positivity in the prostatic secretion in 68% of cases. Therefore antinflammatory antiedemic and decongestant effects of Mepartricine on prostatic inflammation, are observed. CONCLUSIONS: The data of the literature show data estrogens modulate inflammatory reactions: it is possible that their decrease can produce, at prostatic level, antinflammatory effects improving urethro-prostatic bladder functions. Personal experience seems to confirm this supposition and so we think that Mepartri-cine can be considered and excellent coadjuvant in the treatment of prostate inflammation, independent of etiology.

Thalassaemic men affected by erectile dysfunction treated with transurethral alprostadil: case report.

The aim of this controlled clinical study, performed in a specialized institutional unit for thalassaemic men, was to consider the possibility of restoring erection in beta-thalassaemic patients with erectile dysfunction by administering E(1) prostaglandins (alprostadil) transurethrally. Four patients affected by beta-thalassaemia, aged between 32 and 52 years, and having an erectile dysfunction were included in the study. Each patient was given 500 microg alprostadil in the distal urethra. Response was evaluated by the erection assessment scale. The main outcome measures were: (i) the clinical study; (ii) FSH, LH, total and free testosterone plasma concentrations; and (iii) basal and dynamic Doppler sonography of cavernous arteries. The treatment produced a response of 3-4 on the erection assessment scale. Average minimum response time was 20 min, while average maximum response time was about 60 min. There was no evidence of significant side effects. Our hypothesis is that the delayed reaction was due to organ damage induced by iron load, causing a reduction or absence of elasticity in the interstitial tissue of the corpora cavernosa. Thus, we believe that treatment with alprostadil can be considered an effective, non-invasive therapy for thalassaemic patients with erectile dysfunction.

AMS three-piece inflatable implants for erectile dysfunction: a long-term multi-institutional study in 200 consecutive patients.

OBJECTIVES: The aim of this study was to assess the longterm mechanical reliability of AMS (American Medical Systems) three-piece inflatable implants and their impact on patient-partner satisfaction in 200 consecutive patients with erectile dysfunction who underwent surgery in five different institutions. METHODS: Patient charts included in the study were collected and extensively assessed to record pre- and intraoperative data and postoperative complications. All patients and 120 partners were then seen often in the office at a mean follow-up of 59 months (range 6-130) and they were extensively questioned about function of the device and its impact on the couple's sexual life. RESULTS: At the long-term follow-up, 185 patients (92.5%) were still engaging in sexual intercourse with a mean frequency of 1.7/week. Patients and partners reported prosthetic erections as excellent, satisfactory or poor in 96 (48%), 100 (50%) and 4 (2%) cases, and in 20 (17%), 80 (66%) and 20 (17%) cases, respectively. Postoperative sexual activity was considered excellent, satisfactory or poor by 140 (70%), 44 (22%) and 16 (8%) patients and by 34 (28%), 81 (68%) and 5 (4%) partners, respectively. Reasons for patients' complaints included postoperative penile shortening in 60 (30%) cases and poor glandular engorgement in 40 (20%) cases. Partners' main complaint was unnaturalness of the prosthetic erection, a factor reported by 30 (25%) subjects. Complications requiring surgical exploration included infection in 12 patients (6%) and mechanical failure in 8 patients (4%). Kaplan-Meier estimates demonstrated significantly decreased mechanical survival for the Ultrex type of cylinders compared to the CX type of cylinders. CONCLUSIONS: AMS three-piece inflatable implants provide an overall patient and partner satisfaction rate of 92 and 96%, respectively. However, postoperative penile shortening and poor glandular engorgement were the causes of some complaints among the patient population as well as the unnaturalness of prosthetic erection among female partners. In the long-term, mechanically speaking, CX cylinders seem to be more reliable than the Ultrex ones.

[Paroxetine in the treatment of premature ejaculation].

This study evaluated paroxetine as a possible treatment for premature ejaculation. Sixty two patients affected by primary premature ejaculation were randomly assigned to two groups. A and B, and treated with two different treatment schedules. Patients assigned to group A were treated with paroxetine 20 mg p.o. daily for six months; patients assigned to group B were treated with paroxetine 20 mg p.o. daily for fourteen days, and than dose was reduced to 10 mg for a total treatment period of six months. Only one patient reported significative side effects (weakness). Positive clinical results were obtained, at the end of the treatment, in 89 per cent of group A and 88 per cent of group B. In patients with primary premature ejaculation, paroxetine represents, in our opinion, the best therapeutic option for its efficacy and lack of significant side effects.

[Computed tomography evaluation of urothelial carcinomas of the upper urinary tract].

Computed Tomography (CT) is an indispensable noninvasive method for staging transitional cell carcinomas of renal pelvis and ureter. Twenty-seven patients with upper urinary tract tumors were examined and the CT results correlated with histopathologic findings. These tumors exhibit three different development patterns: in our series we identified 17 intraluminal sessile lesions, 6 focal or concentric wall thickenings and finally 7 infiltrating masses; soft-tissue density lesions exhibited in all cases mild contrast enhancement (mean density increase: 38 HU). Even though the attenuation values of tumors do not allow the accurate demonstration of the depth of renal pelvis and ureteral wall invasion, CT can differentiate the lesions which are still confined within the external wall layers (CT1, 17 cases) from those invading the peripelvic-ureteral fat (CT2, 9 cases) or spreading to other organs as well as distant metastases (CT3, 4 cases). Delayed scans can also demonstrate intraluminal lesion extent and sometimes changes of patients' position allow better differentiation of wall outlines from peripheral fat. The overall staging accuracy of CT was 76.66% and its sensitivity was 93.33%. The assessment of lymph node metastases was the major cause of error in the CT evaluation of these tumors.

Extracorporeal shock wave lithotripsy for urinary stone disease: our experience.

The authors report results of an 18 month study on ESWL treatment for calculosis of different tracts of the urinary apparatus. Average success rate is 80%, even if it varies depending on the site and size of the calculus. Surgery and PCN are required only in cases of unsuccessful treatment or particular forms of lithiasis. ESWL has determined advanced in the treatment of renoureteral stones in the last decade. However some significant generalized complications observed in our patients at follow-up raise doubts concerning possible, unforeseable long term effects of ESWL treatment.

[Uroflowmetry in the early diagnosis of postoperative urethral stenosis].

Uroflowmetry is a widely used technique for evaluation of lower urinary tract "obstructions", and urethral strictures (US) are considered a typically late complication after endoscopic or open prostatectomy. The clinical experience of the Department of Urology of Catania University is reported. Uroflowmetry was included in routine checks of prostatic patients after operation (TUR or open surgery) and the tests were performed at 40 and 180 days post-operatively. This proved to be an effective and objective means for early diagnosis of urethral strictures.
