Abstract
To the Editor, Bladder cancer is one of the most common cancers in humans, representing the 7th and 17th type of neoplasm in both genders. Its incidence and mortality are quite heterogeneous in different countries and are due to different risk factors, quality and prevalence of healthcare and the possibility of early diagnosis and treatment of the tumor and its potential recurrences [...].

Abstract
To the Editor, In recent years, alternative solutions have been proposed to obtain effective results comparable to TURP, which is currently considered the gold standard, and laser vapo-enucleation techniques (1, 2), but with the possibility of maintaining sexual functions. In recent years there has been a growing trend towards ejaculation preservation. Although the results of TURP (3), and most laser enucleation techniques are undoubted in the Benign Prostatic Hyperplasia (BPH) and Lower Urinary Tract Symptoms (LUTS) management, they often lack in the preservation of ejaculation. All the alternative recently proposed interventions (Rezum, AquaBeam, Urolift, TPLA, i-TIND, LEST) are procedures considered by some authors to be promising in both managing BPO and preserving sexual functions. However, all these methods are limited by a lack of long-term follow-up that would evaluate the efficacy over time, possible complications related to the method and the correct patient selection for a specific method. The aim of this letter is to summarize the available evidence and provide clinicians with practical recommendations on the use of the brand new minimally invasive techniques for the management of BPO.

Abstract
Purpose Haemorrhagic cystitis may be due to different etiologies with infectious diseases representing an insidious cause to diagnose. The aim of this narrative review is to provide a comprehensive overview of less common but difficult-to-diagnose causes of infectious haemorrhagic cystitis of bacterial, mycobacterial, and parasitic origin, Moreover, we highlight possible diagnostic tools and currently available treatment options in order to give an updated tool for urologists to use in daily practice. Patients and Methods The search engine PubMed was used to select peer-reviewed articles published from 1/Jan/2010 to 31/Aug/2022. Results Bacteria, fungal, TB and schistosomiasis are uncommon causes of haemorrhagic cystitis burdened by high morbidity, especially if not promptly diagnosed. Conclusion Because haemorrhagic cystitis ranges in severity from mild dysuria associated with pelvic discomfort to severe life-threatening haemorrhage, punctual diagnosis, and immediate treatment are essential to avoid further complications.

Abstract
Upper tract urothelial carcinoma (UTUC) constitutes a rare and aggressive entity accounting for 5% to 10% of all urothelial tumors. The importance of stratification and disparities according to ethnicity and age has never been tested in a sufficiently large sample of patients with metastatic UTUC (mUTUC). We conducted this study to address this void, and we hypothesized that the distribution of metastases may vary according to age and ethnicity. Within the Surveillance, Epidemiology, and End Results (SEER) database (2004-2016), we identified 1115 patients with mUTUC. The chi-square and t-test tests were used to examine statistical significance in terms of proportions and mean differences. A total of 925 (83.0%) patients were Caucasians, while 190 (17.0%) were African Americans. Among both ethnicities, lungs were the most common metastatic site (39.1% vs. 48.9%). Brain metastases were infrequent among both ethnicities (1.2 vs. 2.6%; p = 0.13). The trends in the lung metastases decreased with age from 42.3% to 36.6% (p = 0.010) among Caucasians, whereas they increased among African Americans from 34.0% to 51.7% (p = 0.04). Overall, 32.8% of Caucasians and 40.5% of African Americans exhibited more than one metastatic site. Among Caucasians, increasing age was associated with lower rates of having multiple metastatic sites (from 34.3% to 30.2%) (p = 0.004). According to our multivariable analyses, younger age was associated with an increased risk of lung (OR: 1.29, 95% CI 1.04-1.71; p = 0.045) and bone metastases (OR: 1.34, 95% CI 1.07-1.79; p = 0.046). Racial differences exist in the distribution of mUTUC metastasis and vary according to age. Our findings may also be considered in the design of randomized trials.

Abstract
To the Editor, Bladder cancer (BCa) is the second most common cancer in urological clinical practice, after prostate adenocarcinoma. Usually occurs in patients between 60 and 70 years old, three times more frequently in men than women. About 75% of bladder cancer are pTa or pT1, even more frequently considering a population younger than 40 years old. Early detection is of paramount importance since allows to find tumors when they are still superficial and therefore with a better prognosis.

Abstract
Objective: We describe an original minimally invasive penile plication technique with scrotal or infrapubic access, not requiring circumcision, for penile curvature of different severity and types. This technique can be used to correct both congenital and acquired curvatures, mono or bidirectional deformities. Materials and methods: Between 2012 and 2018 we treated 134 patients suffering from congenital curvature (33) and acquired curvature from Peyronie's disease (101). The average curvature was 62.2° (± 30.4°). Preoperative evaluation included prostaglandin E1 injection with photographic documentation and measurement of penile angulation, administration of IIEF- 15, vasoactive penile Doppler ultrasound, analysis of thermal and vibratory sensitivity with Genito-Sensory-Analyzer (GSA) and assessment of nocturnal penile stiffness with Rigiscan, performed twice, for a detailed evaluation of patient’s erectile function. Scrotal access was performed in patients with dorsal and/or lateral penile curvature; the infrapubic access was performed in patients with ventral curvature. After preparation and incision of Colles’ fascia, penis was partially degloved and an original plication technique called "binary corporoplasty" was performed at the site or sites established at preoperative assessment, with non-resorbable synthetic multifilament (Premicron®) suture. Results: Complete correction of penile curvature was achieved in 96.8 % of patients. No major complications were reported, and no patients suffered worsening in erectile function or in penile sensitivity. The average shortening of convex side was 1.65 cm (± 0.7 cm) and all patients report easy intercourse after correction. The average time of surgery was 46 minutes (± 11 min) and all procedures were performed as a day-hospital or ambulatory settings, with local anesthesia and light sedation. Overall satisfaction rate is 96%. Conclusions: This is a simple and rapid technique that perfectly corrects even the most severe and complex penile curvatures. In comparison to traditional techniques, such as Nesbit procedure, this technique is associated with low morbidity, a very low recurrence rate and a great aesthetic results. Aesthetic and functional patients’ satisfaction was excellent.

Abstract
Introduction: We report our long experience in the surgical treatment of patients requesting penile lengthening by suspensory ligament release and placement of a custom-made soft silicone pubo-cavernous spacer. The aim was to show that with this surgical technique the results obtained are maintained over time. It is crucial to achieve postoperative satisfaction of these patients who show fragility and self-esteem problems. Methods: From 1999 to 2020, we treated 245 patients with congenital or acquired penile brevity. We carefully analysed the preoperative and postoperative (at 6, 12, 24 and 48 months) penile size of the patients to evaluate whether this technique could allow the long-term maintenance of aesthetic results. We also assessed preoperative erectile function and we focused on the psychological aspects to avoid surgery in patients with dysmorphophobia. This original technique involves the section of the suspensory ligament and the implantation of a silicone spacer between the pubic symphysis and the corpora cavernosa. This spacer is conformed to the patient anatomy and maintains the relationship between the anatomical structures unchanged over time. Sexual self-esteem and patient satisfaction were assessed with the APPSSI questionnaire. Results: The mean increase in penile length was about 2.5 cm in flaccid state and 1.9 cm in stretched state. There were no injuries of the neurovascular bundle or urethra, and no erectile dysfunction was noted. These results persisted at 6, 12, 24 and 48 months without significant differences. Over 80% of patients stated that they were completely satisfied with the results obtained. This satisfaction remained stable along follow up. Conclusion: The section of the suspensory ligament and the implant of the soft silicone spacer provide real penis elongation with satisfactory results that persist over time. This technique avoids the frequent complication of short-term shortening due to the scar adhesions of the edges of the dissected ligament. The high aesthetic satisfaction of patients is stable at controls at 6, 12, 24 and 48 months.

Abstract
Objective: Pre-operative assessment of renal stones is essential in selecting treatment options and achieving high success rates for retrograde intrarenal surgery (RIRS). Several nephrolithometric scoring systems have been developed using pre-operative clinical data and stone characteristics. Resorlu-Unsal stone score (RUSS) is composed of four different parameters, and each of them adds 1 point to the final score. One point is added in patients with stone size > 20 mm, lower calyceal stones and infundibulo-pelvic angle < 45°, stone number > 1, and abnormal anatomy, respec-tively. RUSS categorizes patients into four distinct groups and aims to predict stone-free rates (SFR) after RIRS. We externally validated RUSS and evaluated its predictive accuracy.Materials and Methods: We performed a retrospective analysis of patients who underwent RIRS for renal stones between January 2020 and December 2021. Patient age, pre-operative hydronephrosis, stone size, stone density as Hounsfield Unit(HU), operative time and RUSS were investigated as potential preoperative predictive factors for stone-free status. RUSS was applied to all patients, and the nomogram was externally vali-dated. Area under the curve (AUC) was used for clinical validity assessment.Results: The present study included a total of 79 patients. Mean patient age was 55.1 ± 15.4 years with a mean stone size was 14.2 ± 4.4 mm. Overall, 62/79 (78.4%) patients were stone free after the initial treatment. After applying RUSS, 36 (45.6%), 29 (36.7%), 10 (12.6%), and 4 (5.1%) patients had a score of 0, 1, 2, and 3, respectively. On multivariate logistic regression RUSS (OR = 0.220; 95%CI: 0.086-0.567; p = 0.002) was identified as the only predictor of postoperative stone-free status.Conclusions: RUSS is a user-friendly scoring system that may predict postoperative stone-free rate after RIRS with great effi-cacy and accuracy.

Abstract
INTRODUCTION Bladder cancer is one of the most common tumors among the general population. The first surgical approach to the tumor is often the transurethral resection with monopolar or bipolar loop. Recently, laser energy has become an alternative for resection of small bladder tumor, because it allows to obtain high quality samples with the "en bloc" technique. Our study aims to show the results of endoscopic diode laser treatment of bladder tumor up to three centimeters in maximum diameter. MATERIALS AND METHODS 189 patients underwent "en bloc" resection with diode dual length laser (980 nm-1470 nm). Follow up was over 12 months. Patients age range was from 45 to 75 years. Maximum diameter of the lesions was 3.0 cm. For each patient, a cold forceps biopsy sample was performed. RESULTS All samples collected presented detrusorial layer. Pathological exam showed: 28 (14.8%) Ta, G1-G2; 7 (3.7%) T3, G2-G3; 14 (7.4%) T1, G2-G3 and 140 ( 74.1%) Ta, G2-G3. No complications occurred during or after surgery. At a median follow-up period of 6 months, we had no recurrence in the previous site of tumor. In the follow up at 3/6/12 months in 4 cases we had recurrence in different sites of bladder wall. CONCLUSIONS Laser "en bloc" resection is an effective, feasible, and safe treatment for bladder tumor. It could be a valid alternative to monopolar and bipolar resection in small bladder cancer treatment.

Abstract
BACKGROUND One of the greatest challenges in semi-rigid ureteroscopies, for both stones and tumors, is the control of endoscopic vision and the maintenance of low intracavitary liquid pressure. We present a comparison between two operative techniques: in the first method an ordinary guide wire (diameter 0.032'') is used for the procedure; in the second one a 5 Fr ureteral catheter replaces the guidewire (we called it "Active guidewire") Methods We compared 50 semirigid ureteroscopies (sURS) performed using the active guidewire with another 50 procedures conducted with a classic guidewire. We evaluated the difference in operating times, quality of endoscopic vision, periprocedural infections rate and stone-free rate. RESULTS The use of active guidewire has considerably reduced the standardized operating times per unit stone-volume by about 39%. Vision quality has improved considerably thanks to the continuous flow in-and-out. Consequently, periprocedural infections decreased (3% vs 30%) and the stone-free rate rose from 86% to 92%. DISCUSSION AND CONCLUSIONS Employing an "active guidewire" instead of the standard guidewire, the risk of complications related to high pressures and operating time is considerably lower, as well as better treatment quality thanks to the cleaner vision. This technique has proven to be safe as well as easy to apply, and in our belief is to be preferred whenever the ureter accepts without forcing, both the presence of the catheter and the semi-rigid 7 F ureteroscope.

Abstract
Hyperspectral Raman images of human prostatic cells have been collected and analysed with several approaches to reveal differences among normal and tumor cell lines. The objective of the study was to test the potential of different chemometric methods in providing diagnostic responses. We focused our analysis on the ν(CH) region (2800-3100cm-1) owing to its optimal Signal-to-Noise ratio and because the main differences between the spectra of the two cell lines were observed in this frequency range. Multivariate analysis identified two principal components, which were positively recognized as due to the protein and the lipid fractions, respectively. The tumor cells exhibited a modified distribution of the cytoplasmatic lipid fraction (mainly localized alongside the cell boundary) which may result very useful for a preliminary screening. Principal Component analysis was found to provide high contrast and to be well suited for image-processing purposes. Self-Modelling Curve Resolution made available meaningful spectra and relative-concentration values; it revealed a 97% increase of the lipid fraction in the tumor cell with respect to the control. Finally, a univariate approach confirmed significant and reproducible differences between normal and tumor cells.

Abstract
Fluoride-releasing restorative dental materials can be beneficial to remineralize dentin and help prevent secondary caries. However, the effects of fluoride release from dental materials on the activity of dental pulp stem cells are not known. Here we investigate whether different fluoride release kinetics from dental resins supplemented with modified hydrotalcite (RK-F10) or fluoride-glass filler (RK-FG10) could influence the behavior of a human dental pulp stem cell subpopulation (STRO-1(+) cells) known for its ability to differentiate toward an odontoblast-like phenotype. The 2 resins, characterized by similar physicochemical properties and fluoride content, exhibited different long-term fluoride release kinetics. Our data demonstrate that long-term exposure of STRO-1(+) cells to a continuous release of a low amount of fluoride by RK-F10 increases their migratory response to transforming growth factor β1 (TGF-β1) and stromal cell-derived factor 1 (SDF-1), both important promoters of pulp stem cell recruitment. Moreover, the expression patterns of dentin sialoprotein (dspp), dentin matrix protein 1 (dmp1), osteocalcin (ocn), and matrix extracellular phosphoglycoprotein (mepe) indicate a complete odontoblast-like cell differentiation only when STRO-1(+) cells were cultured on RK-F10. On the contrary, RK-FG10, characterized by an initial fluoride release burst and reduced lifetime of the delivery, did not elicit any significant effect on both STRO-1(+) cell migration and differentiation. Taken together, our results highlight the importance of taking into account fluoride release kinetics in addition to fluoride concentration when designing new fluoride-restorative materials.

Abstract
Prostate specific antigen (PSA) is still the best available tumour marker in prostate cancer (PCa), but presents some limits. Therefore, there is a need for novel markers in the detection and management of PCa. The 80-kDa soluble form of E-cadherin (sE-cad) and the cytokine IL-6 are being discussed as supplemental serum markers for PCa. In this study, sE-cad and IL-6 serum levels were determined in patients with pathological localized or locally advanced PCa without any previous treatment. These patients underwent radical retropubic prostatectomy (RRP) in accordance with the EAU Guidelines on Prostate Cancer. The molecules were determined via immunoenzymatic assays in samples collected before and after surgery. Statistical analysis was performed by Student's t-test and Pearson's correlation test. sE-cad levels were 6.0 ± 2.7 and 4.6 ± 2.3 µg/ml, before and after RRP, respectively. A highly statistically significant decrease in sE-cad concentrations after RRP was observed (p<0.0001), in 50/61 patients (82%). sE-cad levels before and after surgery were correlated (Pearson's correlation coefficient, r=0.6993, p<0.0001). sE-cad values detected after surgery were higher in patients with PSA levels >10 ng/ml (p<0.05). sE-cad levels before RRP were significantly higher in patients with G3 tumours compared to those with G2 tumours (p<0.02). Finally, sE-cad concentrations both before and after surgery were higher in tumours with Gleason score =7 compared to those with Gleason score <7 (p<0.002 and p<0.05, respectively). Preliminary data from 20 patients indicated a statistically significant increase in IL-6 levels after RRP (11.2 vs. 7.2 pg/ml, p<0.001). This is the first study on the reduction in sE-cad levels after RRP in PCa patients. Moreover, it shows that preoperative sE-cad concentrations are higher in patients with less differentiated PCa. Promising findings of this pilot study may lead to investigation of sE-cad in a larger study with follow-up.

Abstract
Despite recent improvements in detection and treatment, prostate cancer continues to be the most common malignancy and the second leading cause of cancer-related mortality. Thus, although survival rate continues to improve, prostate cancer remains a compelling medical health problem. The major goal of prostate cancer imaging in the next decade will be more accurate disease characterization through the synthesis of anatomic, functional, and molecular imaging information in order to plan the most appropriate therapeutic strategy. No consensus exists regarding the use of imaging for evaluating primary prostate cancer. However, conventional and functional imaging are expanding their role in detection and local staging and, moreover, functional imaging is becoming of great importance in oncologic management and monitoring of therapy response. This review presents a multidisciplinary perspective on the role of conventional and functional imaging methods in prostate cancer staging.

Abstract
BACKGROUND Chronic inflammation and subsequent tissutal alterations may play a key role in prostate carcinogenesis. In this way, molecular alterations of the suppressor of cytokine signaling 3 (SOCS3), one of the most important inhibitory molecule of inflammatory signal transduction circuitries, could contribute to explain the pleiotropic role of interleukin-6 (IL-6) in this type of cancer. METHODS We analyzed the methylation status and mRNA expression of SOCS3 in 20 benign prostate hyperplasias (BPH) and in 51 prostate cancer specimens. We analyzed the SOCS3 methylation status using methylation-specific PCR. Hypermethylation was confirmed by sequencing after subcloning. Epigenetic silencing of this gene was also demonstrated by real-time PCR and by immunohistochemistry. Results and correlation with clinical data were statistically analyzed. RESULTS We found that the promoter of SOCS3 was methylated in 39.2% of prostate cancer. On the contrary, all BPH and normal controls had an unmethylated pattern. Real-time analysis showed that in methylated cases SOCS3 mRNA expression was reduced by three and four folds as compared to BPH and unmethylated cases, respectively. Interestingly, SOCS3 mRNA level was higher in unmethylated prostate cancer than in BPH. The immunohistochemical staining analysis for SOCS 3 confirmed mRNA results. Moreover, methylation of SOCS3 promoter significantly associated with intermediate-high grade Gleason score (P = 0.0007) and with an unfavorable clinical outcome (P = 0.0019). CONCLUSIONS Our data suggest that SOCS3 hypermethylation may be involved in the pathogenesis of prostate cancer and could identify a tumor subset with an aggressive behavior.

Abstract
Several substances such as growth hormone (GH), erythropoietin (Epo), and anabolic steroids (AS) are improperly utilized to increase the performance of athletes. Evaluating the potential cancer risk associated with doping agents is difficult since these drugs are often used at very high doses and in combination with other licit or illicit drugs. The GH, via its mediator, the insulin-like growth factor 1 (IGF-1), is involved in the development and progression of cancer. Animal studies suggested that high levels of GH/IGF-1 increase progression of androgen-independent prostate cancer. Clinical data regarding prostate cancer are mostly based on epidemiological studies or indirect data such as IGF-1 high levels in patients with prostate cancer. Even if experimental studies showed a correlation between Epo and cancer, no clinical data are currently available on cancer development related to Epo as a doping agent. Androgens are involved in prostate carcinogenesis modulating genes that regulate cell proliferation, apoptosis and angiogenesis. Most information on AS is anecdotal (case reports on prostate, kidney and testicular cancers). Prospective epidemiologic studies failed to support the hypothesis that circulating androgens are positively associated with prostate cancer risk. Currently, clinical and epidemiological studies supporting association between doping and urological neoplasias are not available. Nowadays, exposure to doping agents starts more prematurely with a consequent longer exposition period; drugs are often used at very high doses and in combination with other licit or illicit drugs. Due to all these elements it is impossible to predict all the side effects, including cancer; more detailed studies are therefore necessary.

Abstract
Androgens are involved in the development and progression of prostate cancer even if the mechanism is not well-recognized. For this reason androgen-deprivation therapy remains a milestone for the treatment of patients with advanced and metastatic disease and, in the last years, in conjunction with radiotherapy and surgery in locally advanced tumors. Alternative options, such as intermittent deprivation suppression, seem to be promising in terms of clinical benefits and toxicity profile. However, current therapies present side effects, such as testosterone surge with consequent clinical flare-up, metabolic syndrome and hormone-resistance, which develops after a variable number of years. Novel therapies such as LH-RH antagonists and prolonged depot LH-RH analogues have been developed in order to avoid clinical flare-up and testosterone microsurges. Novel androgen synthesis inhibitors, such as abiraterone acetate and MDV3100, have been recently discovered and tested as promising hormonal second-line agents in patients with castration-resistant prostate cancer. Finally, long-term side effects from androgen deprivation, such as osteoporosis, sarcopenic obesity and cardiovascular morbidity should be carefully monitored and properly treated.

Abstract
Purpose Congenital abnormalities and acquired disorders can lead to organ damage and loss. Nowadays, transplantation represents the only effective treatment option. However, there is a marked decrease in the number of organ donors, which is even yearly worsening due to the population aging. The regenerative medicine represents a realistic option that allows to restore and maintain the normal functions of tissues and organs. This article reviews the principles of regenerative medicine and the recent advances with regard to its application to the genitourinary tract. Recent findings The field of regenerative medicine involves different areas of technology, such as tissue engineering, stem cells and cloning. Tissue engineering involves the field of cell transplantation, materials science and engineering in order to create functional replacement tissues. Stem cells and cloning permit the extraction of pluripotent, embryonic stem cells offering a potentially limitless source of cells for tissue engineering applications. Most current strategies for tissue engineering depend upon a sample of autologous cells from the patient's diseased organ. Biopsies from patients with extensive end-stage organ failure, however, may not yield enough normal cells. In these situations, stem cells are envisaged as being an alternative source. Stem cells can be derived from discarded human embryos (human embryonic stem cells), from fetal tissue or from adult sources (bone marrow, fat, skin). Therapeutic cloning offers a potentially limitless source of cells for tissue engineering applications. Regenerative medicine and tissue engineering scientists have increasingly applied the principles of cell transplantation, materials science and bioengineering to construct biological substitutes that will restore and maintain normal function in urological diseased and injured tissues such as kidney, ureter, bladder, urethra and penis. Conclusions Regenerative medicine offers several applications in acquired and congenital genitourinary diseases. Tissue engineering, stem cells and, mostly, cloning have been applied in experimental studies with excellent results. Few preliminary human applications have been developed with promising results.

Abstract
Recent studies suggest a close relationship between cell metabolism and apoptosis. We have evaluated changes in lipid metabolism on permeabilized hepatocytes treated with truncated Bid (tBid) in the presence of caspase inhibitors and exogenous cytochrome c. The measurement of beta-oxidation flux by labeled palmitate demonstrates that tBid inhibits beta-oxidation, thereby resulting in the accumulation of palmitoyl-coenzyme A (CoA) and depletion of acetyl-carnitine and acylcarnitines, which is pathognomonic for inhibition of carnitine palmitoyltransferase-1 (CPT-1). We also show that tBid decreases CPT-1 activity by a mechanism independent of both malonyl-CoA, the key inhibitory molecule of CPT-1, and Bak and/or Bax, but dependent on cardiolipin decrease. Overexpression of Bcl-2, which is able to interact with CPT-1, counteracts the effects exerted by tBid on beta-oxidation. The unexpected role of tBid in the regulation of lipid beta-oxidation suggests a model in which tBid-induced metabolic decline leads to the accumulation of toxic lipid metabolites such as palmitoyl-CoA, which might become participants in the apoptotic pathway.

Abstract
OBJECTIVE To establish the incidence of prostate cancer (PCa) in Sicily in patients who entered an early detection protocol. METHODS From February 2002 to February 2004, 16,298 subjects aged 40-75 entered the protocol. Patients with suspicious DRE, PSA>10 ng/ml, PSA<or=2.5 ng/ml, from 2.6 to 4 ng/ml or from 4.1 to 10 ng/ml with F/T PSA of <or=15%, <or=20% and <or=25% respectively underwent needle biopsy according to an extensive protocol. RESULTS 3266 patients were eligible for biopsy; PSA was <or=4 in 12.7% and <or=10 ng/ml in 63.9% of patients. A PCa was found in 1171 cases (36.9%) with a relationship between PCa incidence and PSA and age respectively (chi2-test, p<0.0001); 51.8% of patients with PCa had a PSA<10 and 8.8% a PSA<4 ng/ml; 49% were clinically staged as T1c. The estimated odds ratios for each age group showed increased risk for PCa in the fourth decade with PSA between 2.6 and 4 ng/ml (12.5 times higher) and in the fifth decade with PSA between 4.1 and 10 ng/ml (6.2 times higher). CONCLUSIONS Age and serum PSA levels are the major risk factors for PCa. On their basis it is possible to modulate the most suitable timing for early diagnosis in individual patients.

Abstract
PURPOSE This study was conducted by nine urology departments in southern Italy to assess the efficacy of and tolerance to treatment of recurrent urethral stricture using a permanent prosthesis. PATIENTS AND METHODS Since 1992, 99 prostheses have been implanted to treat inflammatory and iatrogenic (seven departments) or all types (two departments) of urethral strictures. The Urolume Wallstent was used in 94 cases. Three centers implanted more than one prosthesis when this was indicated. Local anesthesia was used by six centers, spinal anesthesia by two, and local or general by one. At three centers, urethrotomy was performed immediately prior to implantation; two centers used dilation to 30F, and two centers performed urethrotomy 24 or 36 hours before implantation. The median follow-up is 29.1 months (range 3-53 months). RESULTS The results were good in 52%, fair in 34%, and poor in 14% of patients. The maximum flow rate increased >75% in 82% of patients. All departments reported complete reepithelialization of the urethra by 6 months. The short-term complications (7-28 days) were perineal discomfort (86%) and dribbling (14%). The long-term complications were painful erection (44%), mucous hyperplasia (44%), recurring stricture (29%), and incontinence (14%). All departments performed resection for hyperplasia in many cases. CONCLUSION Permanent urethral endoprostheses can produce excellent results in patients with recurrent urethral strictures.
