Abstract
Introduction Prostate biopsy is nowadays one of the most frequent diagnostic procedures in urology. The incidence of bacteraemia, bacteriuria and infective complications is higher after the transrectal procedure than after the transperineal one. A survey demonstrated that 98% of the urologists in USA use antibiotics to prevent infective complications. The transrectal prostate biopsy is the only diagnostic intervention procedure in urology for which an antibiotic prophylaxis is recommended, also for low-risk patients, by the guidelines of the European Association of Urology. If the perineal route is adopted, the antibiotic prophylaxis is recommended only in high-risk patients. Materials and Methods The patient should preferably receive an evacuative enema to achieve a rectal cleansing and to ameliorate the diagnostic accuracy of transrectal ultrasound. A survey in the US demonstrated that an evacuative enema with saline solution is adopted by more than 80% of urologists. Criteria for antibiotics choice. The majority of bacteraemias are transitory, asymptomatic and self-limiting. On the other side, bacteriuria can persist for several days. Antibiotics must achieve high drug concentrations not only in plasma and tissue but also in urine. Symptomatic infections are generally caused by E. Coli and less frequently by the Streptococcus faecalis. Nevertheless, other agents as Klebsiella and Chlostridium, although rare, might cause severe infections. Thus, prophylaxis needs antibiotics at large spectrum and a single agent may not be enough for high-risk patients. Risk determination and drug schedules. It is essential to point out the infective risk of the patient. The choice of the drug, the timing and schedule of antibiotic prophylaxis are still object of debate. Several randomized studies have been conducted with contradictory results. Results The antibiotic prophylaxis should be tailored according to patients’ infective risk and to the procedure adopted. It is able to reduce infections rate after transrectal biopsy below 5%. The adoption of periprostatic anesthesia and the number of cores can influence the incidence of infective complications. Commonly, one-three days oral administration of fluoroquinolone is adopted. A single-dose prophylaxis can be also used with favorable results. Tolerability and route of administration should be taken into account, and also costs should be considered. Conclusions Considering the low cost of antibiotics adopted as short-term prophylaxis and the high cost of the treatment of infective complications, it seems reasonable to provide antibiotics prophylaxis for all patients at high risk for infective complications and for all cases submitted to transrectal prostate biopsy.

Abstract
We report a technique for the solution of an intraoperative complication occurred during penile prosthetic surgery. Materials and Methods A 70-year-old patient underwent open radical retropubic prostatectomy in 2004 due to a prostate cancer - Gleason 6 (3+3) pT2N0M0. The erectile dysfunction subsequently observed was not responsive to oral or intracavernosal drug administration, so a malleable penile implant surgery was recommended. Results During the positioning of the left penile cylinder, a septum perforation (cross-over) occurred. Instead of interrupting and postpone surgery in order to allow the septum to recover, we decided to proceed utilizing our technique for a safe positioning of the implants. As far as we know, this is the first detailed report on the technique. Conclusions Septum perforation during a penile prosthesis implant does not represent an absolute contraindication to terminating surgery. Our technique allows a safe placing of the cylinders after septum perforation with optimal functional and aesthetic results at long-term follow-up.

Abstract
Introduction The European guidelines classify primary bladder tumors of Ta category and G1–2 grade as low risk tumors when single or less than 7 in number and 3 cm in diameter. The aim of the present paper was to evaluate the usefulness of EORTC Risk Tables when applied to non-selected patients in daily clinical practice. Material and Methods In the present retrospective study 129 consecutive patients affected by primary bladder tumors category Ta and Grade G1–2 have been considered. The median follow-up was 48 months. Bladder tumors were TaG1 in 69 (53.5%) patients, TaG2 in 60 (46.5%), single in 82 (63.6%) and multiple in 47 (36.4%) cases. Fifty-one patients (39.5%) received adjuvant intravesical chemotherapy. Results At a median follow-up of 48 months, 70 (41.8%) patients recurred. Recurrence occurred in 43.5% of TaG1 versus 66.7% of TaG2 tumors (p=0.003), in 50% of single tumors versus 61.7% of multiple (p=0.096), in 41.2% of patients receiving adjuvant chemotherapy versus 62.8% of untreated patients (p=0.007). Progression to G3 grade, T1 category and muscle invasive tumor occurred in 3%, 10% and 2% of cases, respectively. Conclusions The EORTC Risk Tables can be applied in common clinical practice to unselected low-risk patients.

Abstract
Introduction Conservative management is not applicable to all T1G3 tumors. The appropriate treatment should minimize mortality while assuring reduced morbidity and good quality of life. Several attempts have been done to identify categories of T1G3 patients at higher risk. The role of biologic markers is unclear and the prognostic risk factors are mainly clinical. The proper time to abandon the conservative approach in favor of cystectomy is still object of debate. Objectives The aim of the present study is to assess the clinical tumor features showing a detrimental effect on survival, identify the clinical risk factors impacting survival in patients undergoing conservative management of T1G3 bladder tumor, and to analyze the prognostic role of recurrence. Methods The present analysis is extended to 236 patients with T1G3 bladder tumors treated by TUR plus intravesical therapy between 1976 and 2005. Patients with previous T1G3, Tis, more than 3 tumors or greater than 3cm were excluded. Urinary cytology was obtained within 30 days after TUR. Since 2000 re-TUR has been performed. A sequential combination of mitomycin-C (30mg/30ml) and epirubicin (50mg/50ml) was adopted in 106 patients (44.9%). BCG or other agents were given intravesically in 85 (36.0%) and 38 (16.1%) patients, respectively. Seven (3%) patients refused intravescical therapy. In the case of Ta-T1 recurrence, TUR and one year of adjuvant intravesical therapy were repeated. Patients went off study if Tis, T1G3 or T-category tumor over T1 were detected. Age, previous history, number of tumors, re-TUR, adjuvant therapy, recurrence and progression were considered for survival analysis. Results Tumors were primary in 177 (75.3%) and single in 144 (61.5%) cases. At a mean follow-up of 52 months (range: 3–246 months), 116 patients (49.2%) relapsed. The recurring tumor was T1 in 47 (40.5%) cases and T1G3 in 33 (28.4%). In 11 additional patients (9.5%) a Tis was detected. Twenty-five patients (10.6%) progressed and 15 patients (6.4%) underwent cystectomy. Median overall survival was 167 months. The 5-year progression-free survival rate was 87.8%. Thirty-two patients (13.6%) died, 22 (9.3%) for bladder cancer. A higher mortality was detected in recurrent (p= 0.002) and multiple (p=0.009) tumors undergoing conservative management. Survival was decreased by NMI recurrence (p<0.0001) and by progression (p=0.009). No statistical significant difference in survival was evident in relation to the grade and stage of the recurrent tumor. Conclusions Previous positive history and multiplicity are relevant risk factors for survival in patients affected by T1G3 NMI TCCB conservatively treated. Survival is decreased if conservative management is not given up at the time of NMI recurrence, independently from its grade and stage.

Abstract
Introduction and objectives The role of maintenance regimen following early intravesical chemotherapy after TUR of intermediate risk non-muscle invasive bladder cancer (NMI-BC) is still debated. Only few studies have been published on this topic, rarely dealing with patients receiving an early treatment. The aim of the present study is to evaluate the efficacy of one-year maintenance after a 6-week cycle of early intravesical chemotherapy. Methods Between May 2002 and August 2003, 482 patients with intermediate risk NMI-BC after TUR and early intravesical chemotherapy (epirubicin, 80mg/50mL) were randomized between 6-week induction cycle and induction plus maintenance with 10 monthly instillations. A written informed consent was obtained. All patients underwent cytology and cystoscopy 3-monthly for 2 years and 6-monthly thereafter. Results Treatment interruption for toxicity was required in 39 patients. Median follow-up was 48 months. Ten patients (2.5%) progressed and 117 patients (29.6%) recurred. The tumor characteristics were equally distributed between the two arms. No statistically significant difference in recurrence free survival (RFS) was detected between the two arms (p=0.43). An advantage in terms of recurrence free rate (RFR) in favor of the maintenance arm was evident only until 18 months after TUR (p=0.03). A trend for a higher benefit from maintenance in primary and multiple tumors was detected. Conclusions The risk of tumor recurrence is significantly reduced by one-year maintenance only for 18 months after TUR in comparison with patients receiving a 6-week cycle of early intravesical chemotherapy. The disadvantages of prolonged intravesical chemotherapy should be taken into account.

Abstract
OBJECTIVES. There is evidence of a clinical correlation between chronic prostatitis and elevated serum levels of prostate specific antigen (PSA). In the present study a system was developed to stage inflammation in benign prostate hyperplasia (BPH), which correlates with serum PSA. MATERIALS AND METHODS. We retrospectively studied 98 patients undergoing transurethral resection of prostate. In all patients, histological sections of prostate showed BPH and inflammatory cell infiltration, which could be graded as G1, G2 and G3, according to involvement of epithelium. PSA levels were assessed pre- and postoperatively by the Immulite 2000 PSA assay. RESULTS. The difference in mean serum PSA values between groups G1 and G3 was highly significant (G1 = 3.3±2.1; G3 = 7.1±3.9 ng/mL; p<0.05). Mean age, prostatic weight and PSA density were similar in the three groups (p<0.05). CONCLUSIONS. We concluded that in patients with BPH and prostatitis on pathological examination there is an associated PSA elevation when glandular epithelium is disrupted.

Abstract
Microscopic foci of prostatitis may induce prostate-specific antigen (PSA) increase. PSA reduction after antibiotics might identify those patients in whom biopsy can be avoided. Ninety-nine patients received ciprofloxacin for 3 weeks, of whom 59 showed PSA reduction. Histology detected small foci of prostatitis in 65% of cases. Carcinoma was found in 40 and 20.3% of patients with unchanged or decreased PSA, respectively (P=0.03). No cancer was detected if PSA decreased below 4 ng/ml or more than 70%. Biopsy can be postponed, with a low risk of missing a cancer, if PSA decreases more than 70% or below 4 ng/ml.

Abstract
At present, radical prostatectomy is the standard of care for localized prostate cancer. Several mini-invasive urological procedures have been developed during the last years, such as the laparoscopic radical prostatectomy, which is nowadays an innovative technique for urologists. This procedure shows many benefits in terms of anatomic accuracy, reduction of hospitalization and transurethral catheterization, recovery of urinary continence and sexual potency. In this study we have described the laparoscopic radical prostatectomy technique which is carried out by urologists at the “Hôpital Henry Mondor” - Creteil, Paris, where the first author has worked for six months.

Abstract
PURPOSE To prospectively compare contrast material-enhanced ultrasonography (US) with computed tomography (CT) in the classification of complex cystic renal masses with the Bosniak system. MATERIALS AND METHODS Ethics committee approval and written informed consent were obtained. Forty patients (17 women, 23 men; age range, 31-77 years) with 44 complex cystic renal masses detected with conventional US were prospectively examined by using second-harmonic US with a second-generation contrast agent and multiphasic helical CT. Thirty-six patients had one lesion, and four patients had two lesions. Surgical resection in nine patients and imaging follow-up in 31 patients were used to determine the outcome. RESULTS On contrast-enhanced US images, masses were classified as Bosniak category II (n = 18), IIF (ie, lesions were classified as category II and follow-up was needed) (n = 16), III (n = 7), or IV (n = 3) lesions. On CT images, masses were classified as Bosniak category II (n = 24), IIF (n = 10), III (n = 7), or IV (n = 3) lesions. Interobserver agreement was high (kappa = 0.86, P < .001) for classification with US. Complete concordance between the readers was found for classification with CT. Complete concordance between contrast-enhanced US and CT was observed in the differentiation of surgical and nonsurgical complex cysts. Complete concordance among the three readers in the assessment of vascularity with contrast-enhanced US was found. Interobserver agreement in the evaluation of enhancement on CT images was high (kappa = 0.88, P < .001). Concordance between contrast-enhanced US and CT in the evaluation of vascularization was high (kappa = 0.77, P < .001). CONCLUSION The study data suggest that contrast-enhanced second-harmonic US is appropriate for renal cyst classification with the Bosniak system.

Abstract
Objectives Nowadays endorectal probes for Magnetic Resonance Imaging (MRI) have better resolutions, which allows to acquire high-level images of prostate and to improve the MRI sensitivity and specificity to determine the cancer volume and the extraprostatic extension. The objective of the present study is to evaluate the sensitivity and diagnostic accuracy of endorectal MRI for identifying the local extension of prostate carcinoma compared to transrectal sonography (TRUS) of prostate. Materials and Methods The study included 81 patients with clinical suspect of cancer and/or elevated values of serum prostate specific antigen (PSA), who underwent endorectal MRI with 1.5 T endorectal probe before transrectal biopsy. Patients with localized prostate cancer underwent radical surgery. The results of endorectal MRI were compared to those of TRUS and histopathological examination outcomes. Results 15 of the 81 enrolled patients had extraprostatic localization of cancer, which was assessed through TRUS in 4 cases only (26%), and through MRI in 7 cases (46%). A seminal vesicle involvement was present in 10 patients, detected by MRI in 5 cases and in no cases by TRUS. Discussion and Conclusions Data are similar to the findings collected by several Authors. The endorectal MRI has a better accuracy in staging prostate cancer compared to TRUS. Nevertheless, this procedure has some limits: little availability of equipment in hospitals, physicians’ little experience, and higher costs compared to TRUS.

Abstract
Urine is a complex balanced solution containing dissociated and non-dissociated solutes. Any variation in urine saturation grade (number of crystals dissolved in a volume of urine), urinary pH and the concentration of crystallization inhibitors can break the normal existing balance and lead to urolithiasis. In the present article we analyze the principal mechanisms (absorptive, renal, resorptive) of hypercalciuria. It will be also shown how heredity directly influences the clinical aspects of cystine, xanthine and oxalate lithiasis and how diet, in association with metabolic disorders, interferes in uric acid and oxalate stone formation. Finally, we report on the roles of urinary tract malformations, urinary tract infections and drugs in the clinical characterization of urolithiasis.

Abstract
Based on our own experiences and a review of the recent literature, this article evaluates recent developments in predicting outcomes and failures of shockwave lithotripsy when treating patients with urinary tract stones. After a detailed MEDLINE research, the authors identified several variables that influence and predict extracorporeal shockwave lithotripsy (ESWL) success. These variables may be categorized as stone variables, patient variables and operator variables. Only multivariate analysis on a large number of homogenous patients may offer an objective evaluation of the factors conditioning ESWL outcome.

Abstract
OBJECTIVE The distribution of potential environmental risk factors among patients affected by superficial transitional cell carcinoma of the bladder (TCCB) has been analyzed. METHODS Patients affected by superficial TCCB underwent TUR and early intravesical chemotherapy. Detailed data about age, sex, residence, employment, active and passive cigarette smoking, water resource and hair dye use were centralized. Analysis has been conducted on 474 patients affected by Ta-T1 G1-2 TCCB at medium risk for recurrence. Patients with primary single Ta G1-2, Tis or T1G3 tumors were excluded from the present analysis. RESULTS Over 80% of the patients lived in urban areas, 22% were employed in industries presumed at risk for bladder cancer, 8% used hair dye and 75% were smokers. Bottled water was the only water resource in 42% of the patients. Employment in industry at risk (p = 0.01) and cigarette smoking (p = 0.04) resulted in being statistically related to tumor multiplicity. Moreover, the period of cigarette smoking was significantly longer in patients with recurrent tumors (p = 0.026). The municipal water supply represented the main water source in never-smokers (p = 0.01) rather than in smokers and in patients harboring T1 rather than Ta tumors (p = 0.03). CONCLUSIONS Employment in industry at risk and cigarette smoking resulted in being related to tumor multiplicity. The length of exposure to cigarette smoking was related to the natural history of the tumor. A drinkable water source emerged as a risk factor in absence of cigarette smoking.

Abstract
OBJECTIVE Androgen-deprivation therapy (ADT) is the usual treatment for locally advanced or metastatic prostate cancer. Osteoporosis is a common complication of ADT. The aim of our study was to evaluate the efficacy of neridronate, a relatively new bisphosphonate to prevent bone loss during androgen ablation. METHODS Sixty patients with prostate cancer and osteoporosis were enrolled and randomly assigned to 2 different treatment regimes: group A (30 patients) treated with maximum androgenic blockage (MAB), and group B (30 patients) treated with bicalutamide 150 mg. Each group was divided in 2 subgroups A1-A2 and B1-B2. All patients received calcium and cholecalciferol supplements (500 mg of elemental calcium and 400 IU cholecalciferol) daily. The A2 and B2 subgroups were also treated with neridronate (25 mg intramuscular monthly). Lumbar and femoral bone mineral density (BMD) was evaluated by dualenergy X-ray absorptiometry (DXA), both at baseline and after one year of treatment. Deoxypyridinoline (DPD) and bone-alkaline phosphatase (B-ALP) were determined at the beginning, midstudy and at the end. RESULTS Patients treated only with calcium and cholecalciferol (A1, B1 subgroups) showed a marked bone loss after 6, and 12 months, with increased levels of DPD and BALP, compared to baseline values. Patients treated with neridronate (A2 et B2 subgroups) showed unchanged levels of these markers. After one year of treatment, lumbar and total hip BMD decreased significantly in patients treated only with calcium and cholecalciferol (A1 subgroup: -4.9% and -1.9% respectively). BMD did not change significantly at any site in patients treated also with neridronate (A2 subgroup: +1% and +0.8% respectively). Lumbar and total hip BMD did not change significantly (-1.5% and -1% respectively) in B1 subgroup. In B2 subgroup an important increase in lumbar spine and the total hip BMD was shown (+2.5% and 1.6% respectively). No relevant side effects were recorded during our study. CONCLUSION In conclusion, neridronate is an effective and safe treatment in preventing bone loss in men receiving ADT for prostate cancer.

Abstract
Objective The present study was a urodynamic evaluation of schizophrenic patients with urinary incontinence occurring during treatment with atypical antipsychotics Methods A total of 12 schizophrenic patients (mean age = 30.7 years, SD = 6.5) presenting urinary incontinence during treatment with atypical antipsychotics at stable doses underwent urodynamic evaluations. Clinical assessment included the administration of Positive and Negative Syndrome Scale (PANSS) Results Four patients out of 12 presented urodynamic patterns consistent with an overactive bladder, while five patients presented reduced bladder compliance; only three patients showed normal urodynamic patterns Conclusion Detrusor overactivity is a condition associated with urinary incontinence in schizophrenic patients treated with atypical antipsychotics. Urodynamic evaluations can improve our knowledge of the mechanisms that subtend atypical antipsychotic-induced incontinence, an invalidating side-effect with strong repercussion on compliance and rehabilitation in schizophrenic patients.

Neridronate prevents bone loss in patients receiving androgen deprivation therapy for prostate cancer. J Bone Miner Res 2004; 19:1766-70. [PMID: 15476575 DOI: 10.1359/jbmr.040813] [Citation(s) in RCA: 39] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2004] [Revised: 05/19/2004] [Accepted: 06/19/2004] [Indexed: 11/18/2022]
Abstract
UNLABELLED Today, androgen deprivation therapy is a cornerstone of treatment for advanced prostate cancer, although it presents important complications such as osteoporosis. Neridronate, a relatively new bisphosphonate, is able to prevent bone loss in patients with prostate cancer during androgen ablation. INTRODUCTION Androgen-deprivation therapy (ADT) is a cornerstone of treatment for advanced prostate cancer. This therapy has iatrogenic complications, such as osteoporosis. The aim of our study was to evaluate the efficacy of neridronate, a relatively new bisphosphonate, to prevent bone loss during androgen ablation. MATERIALS AND METHODS Forty-eight osteoporotic patients with prostate cancer, treated with 3-month depot triptorelina, were enrolled and randomly assigned to two different treatment groups: group A (n = 24) was treated with a daily calcium and cholecalciferol supplement (500 mg of elemental calcium and 400 IU cholecalciferol), and group B (n = 24) received in addition to the same daily calcium and cholecalciferol supplement, 25 mg of neridronate given intramuscularly every month. All patients also received bicalutamide for 4 weeks. Lumbar and femoral BMD was evaluated by DXA at baseline and after 1 year of therapy; moreover, deoxypyridinoline (DPD) and bone alkaline phosphatase (BALP) were determined at the beginning, midway through, and at the end of the study. RESULTS After 6 and 12 months, whereas patients treated only with calcium and cholecalciferol (group A) showed a marked bone loss, with increased levels of DPD and BALP compared with baseline values, patients treated also with neridronate (group B) had substantially unchanged levels of these markers. After 1 year of treatment, lumbar and total hip BMD decreased significantly in patients treated only with calcium and cholecalciferol (group A), whereas it did not change significantly at any skeletal site in patients treated also with neridronate (group B). No relevant side effects were recorded during our study. CONCLUSIONS Neridronate is an effective treatment in preventing bone loss in the hip and lumbar spine in men receiving ADT for prostate cancer.

Abstract
OBJECTIVE Our purpose was to assess the capacity of contrast-enhanced second-harmonic sonography to detect a pseudocapsule in renal masses compared with conventional gray-scale sonography. SUBJECTS AND METHODS. Thirty-two patients with 40 renal masses suspicious for renal cancer (mean diameter, 3.1 cm) were prospectively studied with contrast-enhanced second-harmonic sonography during IV administration of a second-generation sonographic contrast agent. The sonographic criteria for the presence of a pseudocapsule were a peritumoral hypoanechoic halo on conventional gray-scale imaging and a rim of perilesional enhancement, increasing in the tardive phase of the examination, on contrast-enhanced second-harmonic imaging. Multiphasic helical CT or dynamic MRI or both were performed in all patients. RESULTS Final diagnoses of the 40 renal masses were as follows: hemorrhagic cysts, five; angiomyolipomas, four; lymphomas, four; metastasis from lung cancer, one; and renal cell carcinomas (RCCs), 26. Histologic diagnosis of RCC was surgically obtained in all patients. Nephron-sparing surgery was performed in 12 of 26 RCCs, and radical nephrectomy was performed in the remaining 14. At pathologic examination, pseudocapsule was found in 14 (53.8%) of 26 RCCs. On conventional sonography, the presence of a pseudocapsule was detected in 3 of 14 RCCs (sensitivity, 21%). Sonographic contrast-enhanced harmonic imaging revealed the presence of pseudocapsule in 12 of 14 RCCs (sensitivity, 85.7%). In the remaining 12 RCCs with either absent or extensive neoplastic infiltration of pseudocapsule seen at pathologic evaluation, pseudocapsule was not visible on either conventional or contrast-enhanced second-harmonic sonography. The pseudocapsule was not visible in any of the 14 noncancerous renal masses on either conventional or contrast-enhanced sonography. CONCLUSION Sonographic contrast-specific imaging with a second-generation contrast agent is effective in improving the sonographic visualization of tumoral pseudocapsule. This finding could be useful both in the sonographic diagnosis and in the choice of conservative surgery for renal cell carcinoma. The potential role of second-harmonic contrast-enhanced sonography in the management of renal cell carcinoma should be investigated in larger series and compared with the findings of state-of-the-art MRI and CT.

Abstract
The diagnosis of prostate carcinoma has been monitored in Sicily and Calabria for one year. Material e Methods Twenty-seven urological centres of Sicily and Calabria joined the study. Detailed informations about age, familiarity, PSA, Gleason score and TNM stage at diagnosis were centralized between november 2001 and november 2002. Results 721 patients have been recruited. The median age was 73 years. More than 80% of the patients were older than 65 years. Median PSA was 14 ng/ml. The clinical stage at diagnosis was T1c in 33% of patients and 67% had an organ confined prostate cancer (T1-T2). Familiarity was detected in 8% of cases. Age and PSA at diagnosis in these patients were similar to those of the remaining population. However, only 18% of them had a T1 tumor, emphasizing the delay in diagnosis in these patients. Although only 10% of the patients shows at diagnosis a metastatic tumor, 29% only are fit for radical prostatectomy in according to age, PSA and stage.

Abstract
OBJECTIVES The purpose of this study was to evaluate the role of magnetic resonance (MR) pyelography in patients affected by hydronephrosis due to ureteric stones, in order to identify a pyonephrotic condition. MATERIALS AND METHODS In the last 3 years, 315 patients, who had originally been investigated by ultrasonography, were evaluated with MR pyelography in order to define the etiology of obstruction. In 67 patients hydronephrosis was referred as caused by lithiasis. RESULTS MR pyelography not only confirmed urinary tract dilatation in all patients, but also identified grade and site of obstruction, both in acute dilatation (25 patients) and in chronic obstructions (42 patients). In 7 patients, MR pyelography documented pyonephrosis that was obviously confirmed by nephrostomic drainage. CONCLUSION MR pyelography, made with ultrafast breath-hold sequences, has a great value in identifying hydronephrosis in patients with ureteric stones. Furthermore, it provides the chance to identify pyonephrosis requiring an immediate drainage of the kidney before major complications develop.

Abstract
We selected 63 prostate tumors with Gleason's grade 6 (3+3), commonly showing both tubular and cribrous patterns. We compared in both patterns the expression of two of the most used biologic markers: PCNA and p53, with the aim to verify the validity of the Gleason's grading system to compare the morphologic grade with biologic aggressiveness and prognostic value. We did not find any statistical difference in the protein immunopositivity, indicating that both patterns could have identical biologic behaviour; then we confirmed the validity of Gleason's system for considering both tubular and cribrous patterns as an intermediate grade of tumoral differentiation. Moreover, we found a linear relationship between the increase of PCNA and the accumulation of mutated p53; this datum could confirm the hypothesis that p53 mutation is a late event in prostate carcinogenesis.

Abstract
INTRODUCTION The availability of new pharmacological and surgical options is responsible for important changes in the management of symptomatic benign prostate hyperplasia (BPH). The Sicilian-Calabrian Society of Urology performed a retrospective survey to assess the management of BPH in southern Italy in 1997 and 1998. PATIENTS AND METHODS A 3-page questionnaire was sent to the 36 urological units of these two regions. The real number of patients treated was required. The numbers were checked with data obtained from the Health Regional Offices. RESULTS Twenty-six urological units (72.3%) replied. Almost all patients underwent urinalysis, determination of serum prostate-specific antigen and creatinine levels, and renal and postvoid vesical echography. Uroflowmetry was performed in 69% and transrectal ultrasound in 56% of the patients. International Prostate Symptom Score or other symptom scores were used in 36% of the cases. Out of 31,558 patients with symptomatic BPH, 5,636 were surgically treated. Admission was due to acute urinary retention in 1,324 cases (23.5%). Transurethral resection of the prostate was the commonest procedure, accounting for 59.5% of the interventions. Open prostatectomy was performed in 1,804 patients (32%). Minimally invasive therapies accounted for less than 9% of the treatments. CONCLUSIONS The present survey provides a picture of the current surgical practice in BPH in southern Italy in the late 1990s. Symptom scores are not routinely adopted. The low rate of transurethral prostate resections is in keeping with the worldwide decline. On the contrary, a high rate of open prostatectomies has been detected.

Abstract
The aim of this study is to evaluate diagnostic accuracy of perineal ultrasound versus cystography in patients affected by urinary incontinence (UI). 40 patients affected by UI were evaluated by voiding cystography and by perineal ultrasound through sagittal scans. Bladder floor related to public simphysis, urethro-vesical angle, bladder neck dilatation after an increase of abdominal pressure with or without urine leakage, were checked. The comparison with urinary cystography gave similar results. In our experience perineal ultrasound study of pelvic floor showed, in the evaluation of urinary incontinence, the same accuracy of the urinary cystography. Ultrasound study allows a good visualization of the anatomic structures of the pelvic floor and of the lower urinary tract and a good evaluation of the tissues; it also offers easy performance, low cost, less invasivity and a better compliance.

Abstract
A case of sarcomatoid carcinoma of the bladder is reported herein. Immunohistochemical staining with human pancytokeratin antibody was negative, while vimentin staining was strongly positive, suggesting a diagnosis of sarcoma of the bladder. Further immunohistochemical analysis revealed positivity for AE1/AE3 cytokeratins, permitting a correct diagnosis of sarcomatoid carcinoma of the bladder. It can be difficult to distinguish between sarcomatoid carcinoma, undifferentiated carcinoma and sarcoma, particularly if the biopsy specimens are of small size. In rare cases, sarcomatoid tumors may express epithelial markers different from those revealed by human pancytokeratin staining.

Abstract
OBJECTIVES Contemporary series of open prostatectomies from Western countries are rare. Frequently, the analysis of the outcome of open prostatectomy refers to old experiences or to series from developing countries. Any comparison with transurethral resection of the prostate can be invalidated by complications of open surgery because of the lack of an adequate healthcare system and technology. METHODS The Sicilian-Calabrian Society of Urology performed a retrospective study to assess the surgical management of benign prostatic hyperplasia in Sicily and Calabria in 1997 and 1998. A three-page questionnaire was sent to the 36 urologic units of these two Italian regions with more than 7.5 million inhabitants. RESULTS Twenty-six units (72.3%) replied. Of 31,558 patients treated for symptomatic benign prostatic hyperplasia, 5636 underwent surgery. Open prostatectomy (n = 1804) accounted for 32% of all surgical treatment. The median prostate volume was 75 cm(3) and the median serum prostate-specific antigen level was 3.7 ng/mL. The postoperative median hospitalization time was 7 days. Concomitant low urinary tract disease was present in 25% of the patients. Severe bleeding occurred in 11.6% of open prostatectomies. Blood transfusions were given in 8.2% of cases. Sepsis was reported in 8.6% of the patients. Reinterventions, within 2 years, mainly due to bladder neck stenosis, were reported in 3.6% of cases. CONCLUSIONS The results of the present survey provide a current picture of open prostatectomy. This procedure, even if performed nowadays and in Western countries, shows the same significant rate of early and late complications reported in the past or in less-developed countries.

Abstract
INTRODUCTION The glycoprotein P-170, causing drug efflux from the cells, may represent at least one cause of resistance to most drugs used in intravesical chemotherapy of superficial bladder cancer. MATERIALS AND METHODS GP-170 was retrospectively assessed in 60 patients affected by superficial transitional cell tumours of the bladder. It was assessed by immunohistochemistry in a semiquantitative way by the intensity of staining and by the percentage of positive cells. Correlation of GP-170 expression with G-grade, T-category, multiplicity, recurrence rate and treatment was investigated. In 44 patients recurrence was analysed in relation to GP-170 basal expression and to its variations. The monoclonal antibody JSB1 (DBA) at 1:20 dilution was employed for the GP-170 assay. RESULTS GP-170 expression increases with grade but was lower in multiple tumours. No difference between Ta and T1 categories was detected. GP-170 immunohistochemistry from different portions of the same tumour showed a very marked variability in 35.7% of patients. Seven patients (11.6%) were totally negative for GP-170. No statistically significant correlation was found between recurrence, progression and GP-170 basal expression. Similarly no correlation emerged between grade and stage variations at recurrence and modifications in GP-170 expression. One third of the tumours recurring after chemotherapy were negative for GP-170 in spite of an increase in recurrence rate and other risk factors. CONCLUSION At the present stage of our experience, we have been unable to show that GP-170 is a useful marker for monitoring chemoresistance to intravesical chemotherapy in superficial bladder cancer. Furthermore, GP-170 determination has shown several technical difficulties.

Abstract
AIM The uroflowmetry data of a selected number of patients who took part to the QUIBUS study (366 traces selected after quality control by a central panel of reviewer) were evaluated for their relationships with age, prostate volume, and IPSS and ICS-BPH scores. Waiting time, flow time, voided volume, maximum flow rate (Q(max)) and average flow rate (Q(ave)) were the flow variables considered for analysis. Only measurements with total voided volume exceeding 100 ml were included. RESULTS An increasing percentage of subjects with voided volume <200 ml was observed over 65 years of age. Age did not affect neither Q(ave) nor Q(max )(p = n.s. at correlation analysis). In particular, Q(max)was <15 ml/s in about 70% of patients independently of age. Prostate enlargement was inversely associated with voided volume, Q(max) and Q(ave), showing a worsening of urinary function for increasing values of prostate volume Q(max) was negatively correlated with IPSS total score and with most single items with the exception of two storage symptoms such as repeated urination and nocturia). Accordingly, Q(max) was inversely associated with the total score ICS-BPH for voiding symptoms to a higher extent (r = -0.31, p < 0.01) than with the one for storage symptoms (r = -0.22, p < 0.01). Flow variables were inversely correlated with IPSS-QoL. CONCLUSION Uroflowmetry and IPSS, although not allowing a definitive diagnosis of obstruction, may nonetheless satisfy the clinical need of a rapid, easy and accurate tool for the noninvasive screening of LUTS patients.

Abstract
Bacillus Calmette-Guerin (BCG) is currently employed in the treatment of superficial bladder cancer but, despite its recognized effectiveness in preventing recurrences and progression, the immune mechanisms behind its antitumor activity remain to be delineated. In this study we provide evidence that a prolonged increase in the plasma levels of IL-2, but not IL-1beta, IL-4, IL-10, IL-2R or TNF-alpha occured in patients affected by bladder cancer following effective BCG treatment. Conversely, a drop in circulating IL-2 was consistently associated with tumor relapse. The level of IL-2 was elevated even further 15 days after the last BCG administration in patients who did not experience tumor recurrence, suggesting a prolonged T cell-mediated response against antigens other than BCG. Our results indicate that a specific type 1 immune response plays a major role in the anti-cancer activity of BCG. In addition, monitoring IL-2 plasma levels may offer a useful tool for predicting tumor recurrences.

Abstract
The aim of the present study was to correlate PSA response with subjective response (bone pain and performance status), in patients treated for hormone refractory carcinoma of the prostate. Twenty-four patients were introduced into the study. Median PSA was 198 ng/ml. Symptom score, performance status and PSA were monitored monthly for 3 months and then 3-monthly. Sixteen patients (66%) showed a PSA response (median value 10 ng/ml). In 8 patients (33%) PSA was <4 ng/ml. Eight patients (33%) only had a subjective response. However, 75% of the patients with a PSA value <4 ng/ml had a subjective improvement. On the other hand, subjective response was 25% only in patients in whom PSA value decreased to <50% of the initial value but >4 ng/ml. In conclusion, PSA response is not always related to subjective improvement and does not always implicate a beneficial effect of the therapy for the patient.

Abstract
We report the case of a 73-year-old man admitted to our department with a history of hematuria, right flank pain and increasing weight loss. Ultrasound and excretory urography showed a right upper pole renal mass considered at first as a heteroplastic process. These findings were subsequently confirmed by a CT scan, which also showed another neoplasm with parenchymatous density in front of the first. The patient underwent radical nephrectomy and the histologic examination showed the simultaneous presence in the same kidney of a renal adenocarcinoma, a transitional cell carcinoma and a leiomyosarcoma of the pelvis.

Abstract
In this study the authors have tried to identify some useful parameters for assessing the quality of life after cystectomy: continence, sexual activity, electrolytic and acid-base balance alterations. Factors which could improve the quality of life after cystectomy include improving surgical techniques and the correct practice of informed consent, when the doctor should give as much information as possible on the therapeutic options, specifying the pros and cons and possible complications, while paying particular attention to the psychological aspects.

Abstract
The objective of this article is the presentation of a new device, simple, easy to use, at low cost, for the prevention of postoperative haematoma following surgery of varicose veins of the lower limbs. It consists in a two-part device that functions as an elastic and pneumatic bandage, that wraps thigh and leg, with the knee articulation free and that is placed immediately before the stripping of the saphenous vein when all the surgical wounds are closed, except the supramalleolar one. While the head of the stripper is pulled, the device is inflated by air with a compression of 40-50 mmHg and the last surgical wound is sutured. Pneumatic compression is held for 24-36 hours, allowing the patients to walk and, in the meantime, to control the colour and the temperature of the foot. The advantages of this device are: easy use and low costs; compression on the area of the saphenous vein and of the main collaterals; uniform but moderate pressure on all the limb circumference.

Abstract
We wish to dedicate this review article on radical cystectomy, its complications and their prevention to the memory of Prof. Luciano Giuliani. The article is based on a work written originally by Jim Montie and many other authors for the consensus meeting on bladder cancer held in Antwerp in 1994 and recently published in a booklet entitled “Global strategy for bladder cancer” (1). With the consent of Montie and the other co-authors, we have prepared on updated Italian version, inserting some parts (such as vascular complications) which were treated more superficially in the preliminary text.

Abstract
In the present study the efficacy and safety of pefloxacin (400 mg/5 ml vial) intravenously administrated for surgical prophylaxis was assessed. Nine hundred and fifty-two patients were treated (599 M, 343 F), with a mean age of 57.9 years +/- 18.6 SD, and in all cases surgical prophylaxis was carried out according to the following scheme: short-term with 2 vials (800 mg) 1 h before the operation, repeated at 12 and 24 hours after the operation; long-term 2 vials (800 mg) 1 h before the operation repeated at 12 and 24 hours after the operation and followed by 1 vial every 12 h for other 2 days. The choice between the two schemes was conditioned by the type of operation and by the basic conditions of the patient. Pefloxacin was seen to be effective in preventing the onset of post-surgical infections (97%), also maintaining the clinical parameters considered within normal limits. Safety was also highly satisfactory, since only 22 (2.3%) cases of side effects occurred, particularly involving the gastro-intestinal system. Thus, in conclusion, the validity of pefloxacin in surgical prophylaxis, with special emphasis on its efficacy in elderly and compromised patients is asserted.

Abstract
Cephalosporins do not reach active therapeutical concentrations in the prostatic tissue in patients suffering from chronic bacterial prostatitis. Cefoperazone is an exception. Its efficacy in the treatment of chronic bacterial prostatitis in 20 patients was studied and the concentrations, obtained after intramuscular administration, evaluated in patients who underwent transurethral operation due to prostatic hypertrophy (in 14 patients). The cefoperazone concentrations in the prostate have been evaluated 60, 90 and in some cases 120 min after the administration of the drug and compared to those obtained in serum. The clinical cure has been obtained in 16 patients. The average drug concentration in the prostate after 60 min was 22.8 +/- 13.6 versus 39.8 +/- 20.0 micrograms/ml in serum; 90 min after administration the average concentration in the prostate was 23.2 +/- 14.1 versus 35.7 +/- 18.1 micrograms/ml in serum. The correlation was significant both at 60 min (r = 64, p less than 0.05) and at 90 min (r = 64, p less than 0.05).

Abstract
To distinguish prostatic dysplasia (or adenosis) from well differentiated adenocarcinoma on transrectal needle biopsy, a morphometric study was conducted on 20 cases of adenosis and 20 cases of well differentiated adenocarcinoma of the prostate. About 100 cells for each patient were analyzed by means of a computerized image analyzer, and mean nuclear diameter, mean nuclear area, mean form factor and number of cells in eight classes of nuclear diameter were studied. The best predictors of malignancy (evaluated by means of Receiver Operating Characteristics curves) were mean nuclear area greater than 28 mu2, presence of more than 5% of cells with nuclear diameter greater than 6.15 mu, and mean nuclear diameter greater than 5 mu. Using these diagnostic criteria the probability of malignancy for a positive specimen rises from 14% (pre-test) to 75% (post-test).
