RESUMEN
OBJECTIVE: To present the results of a nationwide survey among urological patients to evaluate their perception of the quality of care provided by residents. METHODS: An anonymous survey was distributed to patients who were referred to 22 Italian academic institutions. The survey aimed to investigate the professional figure of the urology resident as perceived by the patient. RESULTS: A total of 2587 patients were enrolled in this study. In all, 51.6% of patients were able to correctly identify a urology resident; however, almost 40% of respondents discriminated residents from fully trained urologists based exclusively on their young age. Overall, 98.2% patients rated the service provided by the resident as at least sufficient. Urology trainees were considered by more than 50% of the patients interviewed to have good communication skills, expertise and willingness. Overall, patients showed an excellent willingness to be managed by urology residents. The percentage of patients not available for this purpose showed an increasing trend that directly correlated with the difficulty of the procedure. Approximately 5-10% of patients were not willing to be managed by residents for simple procedures such as clinical visits, cystoscopy or sonography, and up to a third of patients were not prepared to undergo any surgical procedure performed by residents during steps in major surgery, even if the residents were adequately tutored. CONCLUSIONS: Our data showed that patients have a good willingness to be managed by residents during their training, especially for medium- to low-difficulty procedures. Furthermore, the majority of patients interviewed rated the residents' care delivery as sufficient. Urology trainees were considered to have good communication skills, expertise and willingness.

OBJECTIVE: To identify meaningful predictors and to develop a nomogram of postoperative surgical complications in patients treated with partial nephrectomy (PN). PATIENTS AND METHODS: We prospectively evaluated 4308 consecutive patients who had surgical treatment for renal tumours, between 2013 and 2016, at 26 Italian urological centres (RECORd 2 project). A multivariable logistic regression for surgical complications was performed. A nomogram was created from the multivariable model. Internal validation processes were performed using bootstrapping with 1000 repetitions. RESULTS: Overall, 2584 patients who underwent PN were evaluated for the final analyses. The median (interquartile [IQR]) American Society of Anesthesiologists (ASA) score was 2 (2-3). In all, 72.4% of patients had clinical T1a (cT1a) stage tumours. The median (IQR) Preoperative Aspects and Dimensions Used for an Anatomical (PADUA) score was 7 (6-8). Overall, 34.3%, 27.7%, 38% of patients underwent open PN (OPN), laparoscopic PN (LPN), and robot-assisted PN (RAPN). Overall and major postoperative surgical complications were recorded in 10.2% and 2.5% of patients, respectively. At multivariable analysis, age, ASA score, cT2 vs cT1a stage, PADUA score, preoperative anaemia, OPN and LPN vs RAPN, were significant predictive factors of postoperative surgical complications. We used these variables to construct a nomogram for predicting the risk of postoperative surgical complications. At decision curve analysis, the nomogram led to superior outcomes for any decision associated with a threshold probability of >5%. CONCLUSION: Several clinical predictors have been associated with postoperative surgical complications after PN. We used this information to develop and internally validate a nomogram to predict such risk.

BACKGROUND: The aim of this study is to evaluate the perioperative and long-term functional outcomes of laparoscopic (LPN) and robot-assisted partial nephrectomy (RAPN) in comparison to laparoscopic radical nephrectomy (LRN) in obese patients diagnosed with renal cell carcinoma. METHODS: Clinical data of 4325 consecutive patients from The Italian REgistry of COnservative and Radical Surgery for cortical renal tumor Disease (RECORD 2 Project) were gathered. Only patients treated with transperitoneal LPN, RAPN, or LRN with Body Mass Index (BMI) ≥30 kg/m2, clinical T1 renal tumor and preoperative estimated glomerular filtration rate (eGFR) ≥60 mL/min, were included. Perioperative, and long-term functional outcomes were examined. RESULTS: Overall, 388 patients were included, of these 123 (31.7%), 120 (30.9%) and 145 (37.4%) patients were treated with LRN, LPN, and RAPN, respectively. No significant difference was observed in preoperative characteristics. Overall, intra and postoperative complication rates were comparable among the groups. The LRN group had a significantly increased occurrence of acute kidney injury (AKI) compared to LPN and RAPN (40.6% vs. 15.3% vs. 7.6%, P=0.001). Laparoscopic RN showed a statistically significant higher renal function decline at 60-month follow-up assessment compared to LPN and RAPN. A significant renal function loss was recorded in 30.1% of patients treated with LRN compared to 16.7% and 10.3% of patients treated with LPN and RAPN (P=0.01). CONCLUSIONS: In obese patients, both LPN and RAPN showcased comparable complication rates and higher renal function preservation than LRN. These findings highlighted the potential benefits of minimally invasive PN over radical surgery in the context of obese individuals.

Purpose: We report our experience with 100 patients who underwent an innovative prostate enucleation technique that spares the complete urethral-plate from the veru montanum to the bladder neck using a low-energy thulium laser emission. The aim of our study was to evaluate the short-term effects of this procedure on ejaculation preservation and urinary obstruction. Materials and Methods: The International Prostate Symptom Index (IPSS), quality of life (QoL), and Male Sexual Health Questionnaire Ejaculatory Dysfunction (MSHQ-EJD) Short Form were used as validated instruments to quantify ejaculatory dysfunction before and 6 months after the surgery. Results: The median IPSS score pre- and postoperatively was 20 and 5, respectively (p < 0.0001); QoL dropped from a median of 4-1 (p < 0.0001); and the mean preoperative maximal flow rate improved significantly (8.5 vs 21.2 mL/min) (p < 0.0001). Furthermore, there was significant reduction in postvoid residual postoperatively (p < 0.0001). Postoperative ejaculatory function was preserved in 92/100 patients (92%). According to the MSHQ-EJD score, patients reported a slight nonsignificant decrease in frequency of ejaculation (item 1), force of expulsion (item 2) and reduction in semen volume during ejaculation (item 3), with the exception of ejaculation discomfort (item 4). Conclusion: According to our results, complete removal of the apical tissue, which has been advocated as an integral part of the so called ejaculatory hood, does not interfere with ejaculation if the ventral lissosphincter remains intact.

Background: Skeletal muscle loss (sarcopenia) has been linked to cancer cachexia and can predict survival in several tumors, including advanced genitourinary malignancies. Objective: To investigate the predictive and prognostic role of sarcopenia in patients with T1 high grade (HG) non-muscle invasive bladder cancer (NMIBC) treated with adjuvant intravesical Bacillus Calmette-Guerin (BCG). Design setting and participants: Oncological outcomes were evaluated for 185 patients with T1 HG NMIBC treated with BCG at two European referral centers. Sarcopenia, identified from computed tomography scans performed within 2 mo after surgery, was defined as a skeletal muscle index of <39 cm2/m2 for women and <55 cm2/m2 for men. Outcome measurements and statistical analysis: The main endpoint was the association between sarcopenia and disease recurrence and progression. Kaplan-Meier curves and multivariable Cox models were built, and the clinical value of any association was assessed using Harrell's C index and decision curve analysis (DCA). Results and limitations: Sarcopenia was present in 130 patients (70%). On multivariable Cox regression analyses that accounted for the effect of standard clinicopathological prognosticators, sarcopenia was independently associated with disease progression (hazard ratio 3.41; p = 0.02). Addition of sarcopenia to a standard model for prediction of disease progression improved the discrimination of the model from 62% to 70%. DCA revealed superior net benefits for the proposed model in comparison to the strategies of treating all or no patients with radical cystectomy, and in comparison to the existing predictive model. Limitations are inherent to the retrospective design. Conclusions: We demonstrated the prognostic role of sarcopenia in T1 HG NMIBC. Pending external validation, this tool could be easily incorporated into existing nomograms for prediction of disease progression to improve clinical decision-making and patient counseling. Patient summary: We looked at the role of loss of skeletal muscle (sarcopenia) as a factor in predicting prognosis for stage T1 high-grade non-muscle-invasive bladder cancer. We found that sarcopenia is a ready-to-use, cost-free marker that could be used to guide treatment and follow-up in this disease, although the results need to be confirmed in other studies.
RESUMEN
Importance: Although active surveillance for patients with low-risk prostate cancer (LRPC) has been recommended for years, its adoption at the population level is often limited. Objective: To make active surveillance available for patients with LRPC using a research framework and to compare patient characteristics and clinical outcomes between those who receive active surveillance vs radical treatments at diagnosis. Design, Setting, and Participants: This population-based, prospective cohort study was designed by a large multidisciplinary group of specialists and patients' representatives. The study was conducted within all 18 urology centers and 7 radiation oncology centers in the Piemonte and Valle d'Aosta Regional Oncology Network in Northwest Italy (approximate population, 4.5 million). Participants included patients with a new diagnosis of LRPC from June 2015 to December 2021. Data were analyzed from January to May 2023. Exposure: At diagnosis, all patients were informed of the available treatment options by the urologist and received an information leaflet describing the benefits and risks of active surveillance compared with active treatments, either radical prostatectomy (RP) or radiation treatment (RT). Patients choosing active surveillance were actively monitored with regular prostate-specific antigen testing, clinical examinations, and a rebiopsy at 12 months. Main Outcomes and Measures: Outcomes of interest were proportion of patients choosing active surveillance or radical treatments, overall survival, and, for patients in active surveillance, treatment-free survival. Comparisons were analyzed with multivariable logistic or Cox models, considering centers as clusters. Results: A total of 852 male patients (median [IQR] age, 70 [64-74] years) were included, and 706 patients (82.9%) chose active surveillance, with an increasing trend over time; 109 patients (12.8%) chose RP, and 37 patients (4.3%) chose RT. Median (IQR) follow-up was 57 (41-76) months. Worse prostate cancer prognostic factors were negatively associated with choosing active surveillance (eg, stage T2a vs T1c: odds ratio [OR], 0.51; 95% CI, 0.28-0.93), while patients who were older (eg, age ≥75 vs <65 years: OR, 4.27; 95% CI, 1.98-9.22), had higher comorbidity (Charlson Comorbidity Index ≥2 vs 0: OR, 1.98; 95% CI, 1.02-3.85), underwent an independent revision of the first prostate biopsy (OR, 2.35; 95% CI, 1.26-4.38) or underwent a multidisciplinary assessment (OR, 2.65; 95% CI, 1.38-5.11) were more likely to choose active surveillance vs active treatment. After adjustment, center at which a patient was treated continued to be an important factor in the choice of treatment (intraclass correlation coefficient, 18.6%). No differences were detected in overall survival between active treatment and active surveillance. Treatment-free survival in the active surveillance cohort was 59.0% (95% CI, 54.8%-62.9%) at 24 months, 54.5% (95% CI, 50.2%-58.6%) at 36 months, and 47.0% (95% CI, 42.2%-51.7%) at 48 months. Conclusions and Relevance: In this population-based cohort study of patients with LRPC, a research framework at system level as well as favorable prognostic factors, a multidisciplinary approach, and an independent review of the first prostate biopsy at patient-level were positively associated with high uptake of active surveillance, a practice largely underused before this study.

INTRODUCTION: The size of penis can cause concern in patients, even if the organ is clinically normal. Additionally, the cost of phosphodiesterase 5 inhibitors (iPDE5) and long waiting lists to access penile prosthesis placement can lead patients to resort to non-medical and potentially dangerous alternatives. One of these dangerous alternatives is the injection of building silicone at the level of the subcutis of the penis or the corpora cavernosa causing the formation of a granuloma that increases the girth and consistency of the penis. CASE REPORT: The article describes the case of a 43-year-old patient who self-injected aedile silicone at the level of his penis in an attempt to achieve greater penile size and greater rigidity. The patient reported that he could not economically afford the iPDE5.The persistence of severe pain in the penis forced the patient to go to a urological examination. The patient subsequently underwent the penile granuloma exeresis procedure and skin reconstruction with scrotal flap. CONCLUSION: The pursuit of sexual well-being can lead some patients to rely on unconventional and potentially harmful techniques. The role of the andrologist and of the scientific society should be to dissuade the patient from using these dangerous methods and to provide valid alternatives accessible to the patient. The economic difficulty in purchasing drugs that facilitate erection or the long waiting lists for the placement of penile prostheses can favor dangerous methods such as penile injection of silicon. There is therefore a clear need to facilitate access to drugs and surgical techniques that favor the patient's sexual well-being.

OBJECTIVES: To describe first clinical results in term of safety, complications and short term efficacy of temporary placement of UVENTA urethral stent in the treatment of urethral and bladder neck strictures. METHODS: UVENTA urethral stent (Taewoong Medical) is a temporary self expandable covered metallic stent. Anti-migration system and different radial force distribution are the two main innovations. This is a retrospective evaluation of UVENTA stent temporary placements for urethral diseases in two urological Centers. RESULTS: 15 patients underwent UVENTA stent placement between 2016 and 2018. Stent placement was easy and quick in all cases. Considering indwelling period: one patient reported urethral pain related to the stent in the first month, three patients had urinary infection treated with antibiotics; temporary stress incontinence was noted in 21% of bulbar-membranous stents; stent migrations was noted in 3 out of 4 bladder neck cases whereas no bulbar-membranous stents migrated. At removal no significant incrustation, stone or tissue ingrowth were noted, as well as new proximal or distal strictures. Stent removal was uncomplicated in all cases. Median follow up is 9.5 months (6-24). Considering strictures overall success rate is 73% (11/15): 82% for bulbar urethra (9/11) and 50% for bladder neck (2/4). CONCLUSIONS: UVENTA urethral stent showed a satisfying safety profile with few and low grade complications. Absence of migration and damage on healthy mucosa are main achievements. Further cases are needed to confirm these results and to really explore its efficacy.
OBJETIVOS: Describir los primeros resultados clínicos en términos de seguridad, complicaciones y eficacia a corto plazo de la colocación temporal de stent uretral UVENTA en el tratamiento de estenosis de uretra y de cuello vesical.MÉTODOS: El stent uretral UVENTA (Taewoong Medical) es un stent metálico temporal autoexpandible. Las dos principales innovaciones son el sistema antimigración y la distribución de la fuerza radial. Esta es una evaluación retrospectiva de la colocación de UVENTA en enfermedades uretrales en dos centros urológicos. RESULTADOS: 15 pacientes recibieron UVENTA entre 2016 y 2018. La colocación del stent fue fácil y rápida en todos los casos. Teniendo en cuenta el periodo de catéter: un paciente describió dolor uretral relacionado con el stent en el primer mes, 3 pacientes tuvieron infección urinaria tratada con antibióticos; incontinencia urinaria de estrés en el 21% de pacientes con stent en uretra bulbomembranosa; la migración de stents se demostró en 3 de 4 casos con estenosis de cuello vesical, mientras, ningún caso de uretra bulbomembranosa migro. Al quitar el stent, no se observó incrustación significativa, litiasis o tejido en crecimiento, así como nuevas estenosis distales o proximales. La retirada del stent no fue complicada en la mayoría de casos. La mediana de seguimiento fue de 9,5 meses (6-24). Considerando la tasa de éxito en global fue de 73% (11/15): 82% para uretra bulbar (9/11) y 50% para cuello vesical (2/4). CONCLUSIONES: El stent uretral UVENTA demostró un perfil de seguridad satisfactorio con mínimas complicaciones. La ausencia de migración o daño de la mucosa sana son las principales virtudes. Son necesarios más casos para confirmar estos resultados y explorar su eficacia.

OBJECTIVE: To evaluate the premalignant potential of high-grade prostatic intraepithelial neoplasia (HGPIN) and atypical small acinar proliferation (ASAP). METHODS: Patients diagnosed with monofocal HGPIN (mHGPIN), widespread HGPIN (≥4 cores, wHGPIN) and/or ASAP who underwent at least one rebiopsy during their follow-up, were enrolled. All enrollment biopsies underwent central pathologic revision. Risks for PCa were estimated using Fine and Gray method for competing risk. RESULTS: Pathologic revision changed the original diagnosis in 32.3% of cases. Among 336 cases enrolled, PCa was diagnosed in 164 (48.8%), and more specifically in 20 (30.3%) mHGPIN, 10 (34.5%) wHGPIN, 101 (54.0%) ASAP, and 33 (61.1%) HGPIN + ASAP (mean follow-up 124 months). Most PCa were Gleason score 6(3 + 3) (51.0%) and 7(3 + 4) (34.3%). On multivariate analysis, HGPIN + ASAP (HR 2.76, p < 0.001) and ASAP alone (HR 2.41, p < 0.001) were the only lesions significantly associated with PCa development. Of all cancers detected, 64.3% were at first rebiopsy. A rebiopsy performed within 3 months after ASAP diagnosis had a 45% chance of finding PCa. At Kaplan-Meier survival curves, median PCa-free survival was 48.1 months for HGPIN + ASAP and 64.9 months for ASAP (p 0.0005 at Log-rank test). At 1 year, 70% of HGPIN + ASAP, 73% of ASAP, 89% of wHGPIN, and 84% of mHGPIN were PCa-free. CONCLUSION: The diagnosis of ASAP and HGPIN strongly relies on the expertise of dedicated uro-pathologists. Finding of ASAP is a strong risk factor for a subsequent PCa diagnosis, advising a rebiopsy, possibly within 3 months. m/wHGPIN should not be routinely rebiopsied.

BACKGROUND: To investigate the perioperative and morbidity outcomes after partial nephrectomy (PN) in patients with short life expectancy (SLE) (≥95% 10-year expected mortality (10y-EM)), to assess the main predictors of outcomes in this population and to compare these results with those of a group at the opposite upper range with long LE (LLE, ≤5% 10y-EM) relying on a multicenter Italian prospective registry of kidney surgery (the RECORD 2 project). METHODS: Clinical data of 4,325 patients undergone kidney surgery were collected at 26 urological Italian Centers from 2013 to 2016. SLE was defined as a ≥95% 10y-EM (assessed using the age-adjusted Charlson comorbidity index [CCI]). A multivariable logistic regression for overall postoperative complications, acute kidney injury (AKI), positive surgical margins (SM) and ∆ estimated glomerular filtration rate (eGFR) ≥25% at 2 years from surgery was performed in patients with SLE including clinically relevant variables. Adjusted outcomes reported as mean (SD) of the 2 groups were generated using separate multivariable logistic regression models and compared. RESULTS: Overall, 559 patients with SLE were selected. Patients had an ASA score ≥3 in 58.4% of cases. A clinical T1a, T1b, and T2 stage was found in 412 (74.5%), 124 (22.4%), and 17 (3.1%) patients. The median PADUA score was 7 (6-8). Surgical and medical postoperative complication rates were registered in 14.8% and 6% cases. Postoperative AKI was reported in 27.3% cases, positive surgical margins (PSM) in 9.3% cases. In this subgroup of patients, ASA score, cerebrovascular disease, surgery in low volume centers, and open surgery were independent predictors of overall complications. ASA and PADUA scores, renal clamping, resection technique and lower eGFR at baseline were independent predictors of AKI. PADUA score, open approach and resection technique were independent predictors of PSM. Cardiovascular disease, hilar clamping, and resection technique were independent predictors of eGFR decrease >25% at 2 years from surgery. Patients with SLE were compared with those with LLE (nâ¯=â¯302). All analyzed parameters at baseline were significantly different among the groups with the exception of cancer laterality. After adjusting for several clinical variables, the SLE group had a significantly higher risk rate of adjusted overall postoperative complication rate compared to the LLE group (20.6% ± 0.36 vs. 9.9% ± 0.65, P < 0.0001), while the overall intraoperative complications (4.1% ±0.13 vs. 2.3% ± 0.23), overall postoperative major complications (3.8% ± 0.09 vs. 1.9% ± 0.14) adjusted AKI (24.2% ± 0.37 vs. 22.6% ± 0.92), positive surgical margins (8% ± 0.22 vs. 6.4% ± 0.49), and 2-year RF loss (13.4% ± 0.17 vs. 12.4% ± 0.74). CONCLUSION: In selected patients with SLE, PN is feasible with an acceptable safety profile that is overall comparable to patients with no LE limitations. While a robotic approach and surgery performed in high volume centers could reduce the risk of complications, an off-clamp approach and a SE surgical technique may decrease the risk of postoperative AKI and of longer term eGFR decrease.

BACKGROUND: Partial nephrectomy (PN) has a non-negligible perioperative morbidity. Comparative evidence of the available surgical techniques is limited. OBJECTIVE: To compare the perioperative outcomes of open, laparoscopic, and robotic PN. METHODS: Data of 2331 patients treated with PN for cT1 renal tumors were extracted from the RECORd2 database, a prospective multicenter project. Multivariable regression models assessed the relationship between surgical technique and surgical margins, warm ischemia time, postoperative complications, and acute kidney injury (AKI). The probability of achieving a modified trifecta (negative margins, warm ischemia time <25min, and no Clavien-Dindo ≥2 complications) was examined for each surgical approach. RESULTS: Minimally invasive techniques had lower rate of Clavien-Dindo ≥2 complications than that of open surgery (odds ratio [OR] for robotic surgery: 0.27; 95% confidence interval [95% CI]: 0.15-0.47, p< 0.0001; OR for laparoscopy: 0.52; 95% CI: 0.34-0.78; p= 0.002). The probability of receiving ischemia was highest for robotic PN (p< 0.001). Among on-clamp PN, laparoscopy had longer ischemia than open (estimate: 1.09; 95% CI: -0.00 to 2.18; p= 0.050) and robotic (estimate: 1.36; 95% CI: 0.31-2.40; p= 0.011) surgery. When compared with open PN, the risk of AKI was roughly halved for patients treated by robotic and laparoscopic surgery (both p< 0.0001). Positive margins rate did not differ between the groups (all p≥ 0.1). The likelihood to achieve a modified trifecta was not affected by surgical technique in the overall population (all p≥ 0.075). In Preoperative Aspects and Dimensions Used for an Anatomical (PADUA) score < 10 lesions, robotic surgery had higher probability of achieving a modified trifecta than open PN (OR: 1.66; 95% CI: 1.09-2.53; p= 0.018) and laparoscopy (OR: 1.34; 95% CI: 0.94-1.90; p= 0.11). CONCLUSIONS: In PADUA<10 renal tumors, robotic PN allows for higher rates of trifecta than open and laparoscopic surgeries. The impact of surgical technique on perioperative outcomes of PN might be limited in more complex lesions. PATIENT SUMMARY: We evaluated the association between surgical technique and perioperative outcomes of partial nephrectomy. In less complex (Preoperative Aspects and Dimensions Used for an Anatomical [PADUA] score < 10) lesions, robotic PN allows for higher rates of trifecta when compared with other surgical techniques.

We present the use of a self-expandable covered metallic stent (UVENTA; TaeWoong Medical, Gyeonggi-do, South Korea) to treat a ureteral stricture after kidney transplant. In this report, we describe the procedure and short-term outcomes of a patient with a recurrent distal stricture who did not respond to percutaneous balloon dilation. We decided to place this temporary stent as an alternative to complex surgery. The aim of the procedure was to get a chronic dilation of the stricture up to 7 mm to stabilize the fibrotic tissue. The procedure was easily and quickly performed by an antegrade and retrograde combined approach. The postoperative course was uneventful. The stent was left in situ for 7 months. No complications were noted, and the renal function remained stable. The stent was easily removed, and 5 months later there were no signs of recurrence. The UVENTA device was shown to be an easy, safe, and effective minimally invasive treatment for ureteral stricture in renal transplant. Proper permanence time and long-term results need to be explored.

Teniendo en cuenta el periodo de catéter: un paciente describió dolor uretral relacionado con el stent en el primer mes, 3 pacientes tuvieron infección urinaria tratada con antibióticos; incontinenciaurinaria de estrés en el 21% de pacientes con stent en uretra bulbomembranosa; la migración de stents se demostró en 3 de 4 casos con estenosis de cuello vesical, mientras, ningún caso de uretra bulbomembranosa migro. Al quitar el stent, no se observó incrustación significativa, litiasis o tejido en crecimiento, así como nuevas estenosis distales o proximales. La retirada del stent no fue complicada en la mayoría de casos. La mediana de seguimiento fue de 9,5 meses (6-24). Considerando la tasa de éxito en global fue de 73% (11/15): 82% para uretra bulbar (9/11) y 50% para cuello vesical (2/4). Conclusiones: El stent uretral UVENTA demostró un perfil de seguridad satisfactorio con mínimas complicaciones. La ausencia de migración o daño de la mucosasana son las principales virtudes. Son necesarios más casos para confirmar estos resultados y explorar su eficacia.(AU)
