- Abstract
Introduction: The aim of our study was to determine the validity of the updated nomogram [Briganti et al.: Eur Urol 2012;61:480-487] as a prediction tool for pelvic lymph node invasion (LNI) in the current era by using a large multicentric population of men who underwent extended pelvic lymph node dissection (ePLND) at the time of radical prostatectomy (RP) at tertiary referral centers., Patients and Methods: Between 2000 and 2011, 896 consecutive patients underwent RP and ePLND at two tertiary referral centers for clinically localized prostate cancer (PCa). Uni- and multivariable logistic regression models predicting the presence of LNI at ePLND were built in. Covariates consisted of preoperative PSA, clinical stage, primary and secondary biopsy Gleason grade with or without percentage of positive cores. Patients' data were entered into a logistic model formula derived from the original publication of Briganti. The nomogram was assessed by comparing its predicted probability of LNI with the actual presence of LNI. The area under the curve was used to quantify its predictive accuracy., Results: Mean preoperative PSA, clinical and pathological stage, primary and secondary biopsy and pathological Gleason grade, such as mean number of total cores, positive cores and percentage of positive cores differed significantly between LNI-positive and LNI-negative patients (all p < 0.001 except for number of total cores, p = 0.019). The mean number of lymph nodes removed was 14.8, and LNI was found in 101 patients (11.8%). In the univariate analysis the percentage of positive cores was the most accurate predictor of LNI (72%), followed by PSA (69%), primary biopsy Gleason grade (64%), clinical stage (60%), and secondary biopsy Gleason grade (59%). The predictions of the nomogram were virtually perfect when the predicted probability was ≤20%. We tested the performance characteristics of various Briganti nomogram-derived cut-offs (1-14%) for discriminating between patients with and without LNI. In our population, 41.6% of patients were classified below the 5% cut-off proposed in the original Briganti et al. report. In the multivariate analysis these variables remained statistically significant predictors for the presence of lymph node metastases. The predictive accuracy of the full model reached 79%., Conclusions: The updated nomogram predicting LNI in patients with PCa undergoing ePLND has been externally validated, demonstrating excellent accuracy and calibration characteristics and a general applicability for predicting the presence of LNI., (Copyright © 2012 S.

- Abstract
Objective: To analyze positive surgical margins (PSM) after radical prostatectomy (RP) in the overall population and in patients previously treated with transurethral resection of the prostate (TURP)., Materials and Methods: 2,408 patients treated with RP for clinically localized prostate cancer (PCa) were consecutively enrolled in 135 departments. We correlated PSM rates and all preoperative, surgical and pathological features. We stratified the site of PSM as unique or multifocal. Moreover, we analyzed differences between 75 patients who had undergone previous TURP and the remaining 2,333 patients., Results: In the entire study population, we identified 702 patients with PSM (29%). Using univariate analysis, we reported a significant correlation between overall PSM and prostate-specific antigen (PSA), stage cT, biopsy Gleason score, number of biopsy cores, number of positive cores, percentage of positive cores and nerve-sparing approach. PSM proved to be strongly dependent on pT in particular in patients with pT2 PCa. When we compared the data from 75 patients previously treated with TURP and those from 2,333 without previous prostatic surgery, a statistically significant difference in margin localization was found. Moreover, we analyzed the 75 patients mentioned above, stratified in incidental PCa diagnosed at TURP or PCa detected with prostate biopsy for PSA rising during the post-TURP follow-up: no statistical differences were found between the 2 groups regarding margin status, even if PSM were more frequent in incidental PCa with no significance deriving from the stratification for PSM location at the apex or base., Conclusion: Men treated with TURP before RP presented an overall incidence of PSM similar to those without previous TURP, but with a higher risk of PSM at the bladder neck and a lower risk of PSM at the prostatic apex., (Copyright © 2013 S.

- Abstract
Introduction: Our study aimed to assess the usefulness of 3D-CT in patients who have undergone radical cystectomy and orthotopic ileal neobladder., Materials and Methods: We performed a CT study with 3D reconstructions in 32 patients 6 months after radical cystectomy and different orthotopic ileal neobladder (8 Studer, group A; 10 Hautmann-Ghoneim, group B; 14 Hautmann with 'double chimney' modification, group C). We evaluated position, shape and volume of neobladder; length of ureters and of afferent limb (in group A), length and diameter of ureteral intramural tunnel (in group B) and length of 'chimney' (in group C); vesico-urethral angle; vesico-ureteral reflux; possible complications., Results: In group A, we observed a renal stone with hydronephrosis, a lateral neobladder and a bilateral vesico-ureteral reflux. In 2 females of group B, neobladder was on the right side and associated in 1 case with a conical shape, hydroureteronephrosis, filling defects and urinary incontinence. In group C, 1 patient had a bilateral vesico-ureteral reflux and 1 had a left hydronephrosis. A pouchocele was detected in 1 patient with vesico-urethral angle less than 120 degrees., Conclusions: 3D-CT is helpful for better displaying the morphology of a new reno-vesical anatomy, and some features seem to be indicative of a predisposition to develop possible complications. It may be useful for surgeons to plan a reintervention to obviate or prevent complications., (Copyright 2009 S. Karger AG, Basel.)

- Abstract
Introduction: To assess the efficacy and evidence-based data in the literature about rehabilitation therapy in patients with post-prostatectomy urinary incontinence., Materials and Methods: An analysis of published full-length papers identified by a Medline search from 1990 through 2004 was carried out. Abstracts published in peer-reviewed journals in the same period of time were also considered., Results: Efficacy, tolerability and safety of rehabilitation therapy were evaluated, according to the available data in the literature, with special regard to randomized controlled trials in order to define a clear-cut, evidence-based efficacy of this form of therapy., Conclusions: Rehabilitation therapy is a simple and safe way of managing post-prostatectomy urinary incontinence. Nonetheless, few randomized controlled studies have been carried out so far to establish its evidence-based efficacy and it is thus not possible to be scientifically sure of its value. It is therefore necessary to undertake well-designed randomized controlled studies, with a large number of patients, a well-matched control group and an adequate follow-up., (Copyright (c) 2006 S.

- Abstract
Objectives: We report our experience with posterior preperitoneal prosthetic hernioplasty for inguinal hernia in patients undergoing concomitant pelvic surgery for prostatic pathologies., Methods: 172 patients with unilateral or bilateral inguinal hernia underwent posterior preperitoneal prosthetic hernioplasty during pelvic surgery for BPH and malignant prostatic pathologies., Results: There was no evidence of hernial recurrence after a mean of 30 months and no complications attributable to the hernial repairs, except for 1 patient who developed a small periprosthetic hematoma and 1 patient with a pelvic lymphocele, both spontaneously resolved., Conclusions: Posterior preperitoneal prosthetic hernioplasty for inguinal hernia combined with pelvic surgery for prostatic pathologies should be applied routinely by urologists because it is a relatively simple procedure and with a very low rate of complications and recurrence., (2005 S.

- Abstract
Introduction: Prostate-specific antigen (PSA) is the most important marker in the detection of prostate cancer, but its reliability is limited by a low specificity. To improve the specificity of PSA, a new parameter, based on the combination of free/total PSA (F/T) with PSA density, is proposed., Materials and Methods: From April 1999 to June 2003, a series of 647 men with high serum PSA levels were submitted to ultrasound-guided multiple prostate biopsies. Total PSA and free PSA were measured by immunoassay (DASIT, Italy). Receiver operating characteristic (ROC) curves of PSA density, F/T and (F/T)/PSA density (F/T divided by PSA/prostate volume) were constructed, and relative specificity and sensitivity were calculated., Results: Prostate cancer was present in 284 cases (137 of them with PSA values between 4 and 10 ng/ml), 31 patientshad intraepithelial neoplasia and the remaining cases showed benign prostatic hyperplasia. Analysis of ROC curves in all examined patients showed that the area under the curve (AUC) for (F/T)/PSA density (0.849) was significantly higher than the AUC for F/T (0.681) (p = 0.012). Similar results were observed in the cases with PSA levels between 4 and 10 ng/ml, where the AUC for (F/T)/PSA density (0.768) was significantly higher than the AUC for F/T (0.610) (p = 0.041). In our study, the prostate cancer risk became very high when (F/T)/PSA density values decreased to <1.5., Conclusion: The use of the (F/T)/PSA density ratio may be useful in the detection of prostate cancer, reducing unnecessary prostate biopsies. A cutoff of 1.5 for the (F/T)/PSA density value is recommended for patients with PSA levels between 4 and 10 ng/ml.

- Abstract
Introduction: The chemical stability of prostaglandin E(1) (PGE(1)) in physiological solution has been studied in different environmental conditions. However, very little data exist regarding the PGE(1) stability and the consequent breakdown products in PGE(1)-based vasoactive cocktails under different environmental conditions., Objective: To evaluate the loss of the therapeutic efficacy of PGE(1) either alone or in combination with other vasoactive substances under different storage conditions., Materials and Methods: Utilizing high performance liquid chromatography the PGE(1) content was evaluated alone and in association with papaverine and papaverine plus phentolamine at temperatures of 2-8 and at 20 degrees C, and after 15, 30, 60, 90 and 120 days of storage using multivariate statistical analysis of variance., Results: We found that the time of storage significantly affects PGE(1) activity. Furthermore, both the storage temperature and cocktail composition had a significant effect on PGE(1) stability. The chromatographic studies did not disclose the presence of the principal degradation products of PGE(1) (PGA(1), PGB(1)). The presence of papaverine and temperature of 20 degrees C have the greatest effect on the degradation of PGE(1 )during the first 30 days of storage., Discussion: Temperature and time are prevalent factors determining the slow and progressive deterioration curve of PGE(1) after 30 days of storage. None of the environmental conditions evaluated was so drastic to determine the presence of PGA(1) and PGB(1)., Conclusion: For clinical use, one should note that PGE(1) maintains 50-80% of its efficacy for about 1 month even if stored at room temperature (20 degrees C) and/or combined with papaverine., (Copyright 2002 S.

- Abstract
Introduction: Italy delayed limiting access to the Faculty of Medicine and the reform of schools of specialization was not accompanied by programming the number of scholarships, so employment expectations are often disappointing. The aim of this study is to analyze the employment prospects of specialists in urology through the development of possible scenarios for the 5-year period 2000-2004., Materials and Methods: We recorded data received from Italian Schools of Specialization in Urology on specialists in the 5-year period 1994-1998. We also tried to obtain a picture of the national distribution of urologists and urological units. Statistical processing was done with SPSS for Windows 5.0., Results: In the last 5 years, 501 urologists were licensed at an average age of 37 years; 535 urological units exist; 2,332 doctors practice urology (2,235 males and 97 females) for a ratio of 1 urologist to 24,500 inhabitants. By comparing the 'entrance' forecast with the potential 'exit', we can hypothesize an annual excess of 80 units. There is no significant correlation between the number of urologists in each structure and the number of inhabitants for each urologist., Conclusions: The present government programme does not take into account continual changes in employment and many other variables when defining the actual need for specialists. For valid predictions, the data we obtain must be updated for at least 5 years., (Copyright 2000 S. Karger AG, Basel)

- Abstract
Seven patients suffering from prostatic cancer were treated with a slow-release D-Trp-6-LHRH preparation for a period of 24-32 months. LH, FSH, PRL and testosterone levels were evaluated before and at the end of treatment and then 40 days later. Baseline and GnRH-, TRH-, and HCG-stimulated hormonal values decreased after treatment. The possibility that a long-term treatment with GnRH analogues induces a sustained suppression of pituitary and testicular function is suggested.

- Abstract
Basal and TRH-stimulated TSH secretion was evaluated in six patients suffering from prostatic cancer, before and after antiandrogenic treatment performed using a long-acting LHRH analogue, D-Trp-6-LHRH. Although serum testosterone values dropped to minimal levels after treatment, TSH secretion remained unchanged. Observed results suggest that pharmacological castration does not affect the regulatory mechanisms involved in the control of TSH secretion.
