Male reproductive health after 3 months from SARS-CoV-2 infection: a multicentric study.

PURPOSE: While SARS-CoV-2 infection appears not to be clinically evident in the testes, indirect inflammatory effects and fever may impair testicular function. To date, few long-term data of semen parameters impairment after recovery and comprehensive andrological evaluation of recovered patients has been published. The purpose of this study was to investigate whether SARS-CoV-2 infection affect male reproductive health. METHODS: Eighty patients were recruited three months after COVID-19 recovery. They performed physical examination, testicular ultrasound, semen analysis, sperm DNA integrity evaluation (TUNEL), anti-sperm antibodies (ASA) testing, sex hormone profile evaluation (Total testosterone, LH, FSH). In addition, all patients were administered International Index of Erectile Function questionnaire (IIEF-15). Sperm parameters were compared with two age-matched healthy pre-COVID-19 control groups of normozoospermic (CTR1) and primary infertile (CTR2) subjects. RESULTS: Median values of semen parameters from recovered SARS-CoV-2 subjects were within WHO 2010 fifth percentile. Mean percentage of sperm DNA fragmentation (%SDF) was 14.1 ± 7.0%. Gelatin Agglutination Test (GAT) was positive in 3.9% of blood serum samples, but no positive semen plasma sample was found. Only five subjects (6.2%) had total testosterone levels below the laboratory reference range. Mean bilateral testicular volume was 31.5 ± 9.6 ml. Erectile dysfunction was detected in 30% of subjects. CONCLUSION: Our data remark that COVID-19 does not seem to cause direct damage to the testicular function, while indirect damage appears to be transient. It is possible to counsel infertile couples to postpone the research of parenthood or ART procedures around three months after recovery from the infection.

Percutaneous puncture during PCNL: new perspective for the future with virtual imaging guidance.

CONTEXT: Large and complex renal stones are usually treated with percutaneous nephrolithotomy (PCNL). One of the crucial steps in this procedure is the access to the collecting system with the percutaneous puncture and this maneuver leads to a risk of vascular and neighboring organs' injury. In the last years, the application of virtual image-guided surgery has gained wide diffusion even in this specific field. OBJECTIVES: To provide a short overview of the most recent evidence on current applications of virtual imaging guidance for PCNL. EVIDENCE ACQUISITION: A non-systematic review of the literature was performed. Medline, PubMed, the Cochrane Database and Embase were screened for studies regarding the use virtual imaging guidance for PCNL. EVIDENCE SYNTHESIS: 3D virtual navigation technology for PCNL was first used in urology with the purpose of surgical training and surgical planning; subsequently, the field of surgical navigation with different modalities (from cognitive to augmented reality or mixed reality) had been explored. Finally, anecdotal preliminary experiences explored the potential application of artificial intelligence guidance for percutaneous puncture. CONCLUSION: Nowadays, many experiences proved the potential benefit of virtual guidance for surgical simulation and training. Focusing on surgery, this tool revealed to be useful both for surgical planning, allowed to achieve a better surgical performance, and for surgical navigation by using augmented reality and mixed reality systems aimed to assist the surgeon in real time during the intervention.

Low-energy high-frequency Ho-YAG lithotripsy: is RIRS going forward? A case-control study.

Retrograde Intra-Renal Surgery (RIRS) plays a primary role in renal stone treatment context. Energy, frequency and width of laser impulse can be modulated by surgeons to achieve better outcomes. In our study, patients with single renal stone sized 10-20 mm were retrospectively divided into two groups. Patients of Group 1 underwent RIRS with Low-Energy (LE) High-Frequency (HF) settings using Lumenis® 120-W high-power Ho:YAG laser. Patients of Group 2 (control) underwent RIRS using "standard" settings by means of Sphinx® Jr 30 W Ho:YAG system. Follow-up was conducted with a CT scan at 3 months after RIRS in both groups. Procedure success was defined as stone-free or presence of ≤ 4 mm fragments (Clinical Insignificant Residual Fragments-CIRF). A total number of 199 patients were included: 86 LE/HF RIRS (Group 1) vs 113 "conventional" RIRS (Group 2). Mean operative time was 56.6 (± 19.4) min in Group 1 vs 65.2 (± 25.2) min in Group 2 (p = 0.01). Mean hospitalization time was 2.5 ± 1.7 days for Group 1 vs 2.9 ± 3.2 days for Group 2 (p = 0.2). Peri-operative complications were counted: eight in Group 1 and 11 in Group 2 (p > 0.05). At 3-month control, stone-free rate was 69% (59/86 patients) in Group 1 vs 65% (73/113 patients) in Group 2 (p = 0.6). Success rate was 93% (80/86) in Group 1 in comparison to 82% (93/113) in Group 2 (p = 0.03). In conclusion, LE/HF RIRS seems to be a feasible and effective technique with a reduction of operative time and optimal results in terms of "stone-free" and "success" rates. Further studies are needed to ensure the validity of our results and to give evidence-based statements.

Aquablation of the prostate: single-center results of a non-selected, consecutive patient cohort.

PURPOSE: Aquablation of the prostate using the AquaBeam™ system promises equivalent functional outcomes, reduced learning curve, and improved sexual function compared to transurethral prostate resection as shown in prospective randomized trials. This prospective cohort study aims to evaluate if published results can be transferred into the clinical routine in a non-selected patient collective. METHODS: This study includes all patients treated between September 2017 and June 2018 with Aquablation of the prostate. Patients have been evaluated prospectively for the perioperative course and early follow-up. Besides voiding parameter and symptom score, TRUS-volume change, ejaculatory function, and adverse events have been recorded. RESULTS: 118 consecutive patients have been treated in the given time. Aquablation could be carried out successfully in all patients. IPSS, QoL, Qmax, and PVR improved significantly after the procedure and continued to improve during 3-month follow-up. Mean OR time was 20 min, TRUS volume decreased by 65%, and 73% of the patients retained antegrade ejaculation. Thirteen adverse events (> Clavien-Dindo I) occurred in 10 patients. CONCLUSION: The surgical ablation of the prostate using Aquablation achieved significant and immediate improvement of functional voiding parameters Qmax and PVR as well as symptomatic improvement of IPSS and QoL. Aquablation seems to be safe and effective with a low perioperative complication profile even in a non-selected group of patients.

The impact of T1 renal tumor characteristics on baseline renal function in patients undergoing partial nephrectomy: A renal scan based objective assessment.

INTRODUCTION AND OBJECTIVES: To objectively assess the impact of renal tumors characteristics and other measurable factors on baseline renal function in patient undergoing partial nephrectomy (PN). METHODS: Patients who underwent laparoscopic PN for a T1 renal mass between 2012 and 2016 and who also had a mercapto-acetyltriglycine renal scan prior to surgery were retrieved from a single institution prospectively-collected database. Split renal function (SRF) and Effective Renal Plasma Flow (ERPF) for both the operated kidney and the unaffected contralateral were calculated. Patient demographics and tumor characteristics (e.g. size, location and; nephrometry score) were assessed. Renal function of both the operated and the unaffected; contralateral kidney were compared. Statistical analysis was performed by using Statistica 8.0 (StatSoft). RESULTS: 227 patients were deemed eligible and included in the analysis. Univariable analysis showed a significant impact of age-adjusted CCI (p = 0.027), hypertension (p = 0.031) and age (p < 0.001) on operated kidney ERPF. Gender (p = 0.011), hypertension (p = 0.042), CCI (both standard and age-adjusted, p = 0.021 and = 0.003, respectively) and age (p < 0.001) were significantly; associated with contralateral unaffected kidney ERPF. Multivariable analysis confirmed age (p < 0.001) and hypertension (p < 0.021) as independent factors in both the operated and the unaffected kidney. CONCLUSIONS: Characteristics of the renal mass (including nephrometry score and size) seem to have no clinically relevant impact on baseline renal function in patients undergoing partial nephrectomy for cT1 renal tumors. Age, hypertension and co-morbidities confirm to represent un-modifiable significant factors influencing baseline renal function.

Predictive factors of overall and major postoperative complications after partial nephrectomy: Results from a multicenter prospective study (The RECORd 1 project).

INTRODUCTION AND OBJECTIVES: To analyze postoperative complications and to assess for significant predictive factors during partial nephrectomy (PN) using a large multicenter dataset. METHODS: Patients who underwent PN for clinical T1 renal tumors at 19 urological Italian centers (Registry of Conservative Renal Surgery [RECORd] project) were evaluated between 2009 and 2012. Anthropometric data, comorbidities and perioperative outcomes were analyzed. Complications were divided as intra- and postoperative, medical and surgical, as appropriate. The severity of postoperative complications was graded according to the modified Clavien classification system. Patients who experienced intraoperative complications were excluded from the analyses for the potential confounding effect in the evaluation of predicting factors for postoperative complications. RESULTS: Overall, 979 patients were analyzed: open, laparoscopic and robot-assisted (available since 2011) surgical approaches were used in 522 (56.4%), 286 (30.9%) and 117 (12.6%) cases, respectively. Surgical postoperative complications were reported in 121 (13.1%) cases (32 (3.5%) were Clavien 3), medical were reported in 52 (5.6%) cases (3 (0.3%) were Clavien 3). No Clavien 4 complications were reported. At multivariable analysis, ECOG score ≥1 (OR 1.98; p = 0.002), lower preoperative hemoglobin (OR 0.71; p < 0.0001) and open surgical approach (2.91; p = 0.02) were significant predictive factors of overall surgical postoperative complications, ECOG score ≥1 (OR 1.93; p = 0.04) and surgical approach (p = 0.05) were significant predictive factors of Clavien 3 either surgical or medical postoperative complications. CONCLUSIONS: Comorbidities and surgical approach should be considered in preoperative evaluation of patients undergoing PN, as they resulted to play a significant role in the occurrence of postoperative complications.

[-2]proPSA versus ultrasensitive PSA fluctuations over time in the first year from radical prostatectomy, in an high-risk prostate cancer population: A first report.

BACKGROUND: [-2]proPSA and its derivatives have an higher diagnostic accuracy than PSA in predicting prostate cancer (PCa). In alternative to PSA, ultrasensitive PSA (uPSA) and [-2]proPSA could be potentially useful in recurrent disease detection. This research focused on [-2]proPSA and uPSA fluctuations over time and their possible clinical and pathological determinants, in the first year after RP. METHODS: A cohort of 106 consecutive patients, undergoing RP for high-risk prostate cancer (pT3/pT4 and/or positive margins), was enrolled. No patient received either preoperative/postoperative androgen deprivation therapy or immediate adjuvant RT, this latter for patient choice. [-2]proPSA and uPSA were measured at 1, 3, 6, 9, 12 months after RP; their trends over time were estimated by the mixed-effects linear model. The uPSA relapse was defined either as 3 rising uPSA values after nadir or 2 consecutive uPSA >0.2 ng/ml after RP. RESULTS: The biochemical recurrence (BCR) rate at 1 year after RP was either 38.6 % (in case of 3 rising uPSA values) or 34.9 % (in case of PSA >0.2 ng/ml after nadir), respectively. The main risk factors for uPSA fluctuations over time were PSA at diagnosis >8 ng/ml (p = 0.014), pT (p = 0.038) and pN staging (p = 0.001). In turn, PSA at diagnosis >8 ng/ml (p = 0.012) and pN (p < 0.001) were the main determinants for [-2]proPSA trend over time. In a 39 patients subgroup, uPSA decreased from month 1 to 3, while [-2]proPSA increased in 90 % of them; subsequently, both uPSA and [-2]proPSA increased in almost all cases. The [-2]proPSA trend over time was independent from BCR status either in the whole cohort as well in the 39 men subgroup. CONCLUSIONS: Both uPSA and [-2]proPSA had independent significant fluctuations over time. PSA at diagnosis >8 ng/ml and pathological staging significantly modified both these trends over time. Since BCR was not confirmed as determinant of [-2]proPSA fluctuations, its use as marker of early biochemical relapse may not be actually recommended, in an high-risk prostate cancer patients population.

Enhanced expression of melanoma progression markers in mouse model of sleep apnea.

INTRODUCTION: Obstructive sleep apnea has been associated with higher cancer incidence and mortality. Increased melanoma aggressivity was reported in obstructive sleep apnea patients. Mice exposed to intermittent hypoxia (IH) mimicking sleep apnea show enhanced melanoma growth. Markers of melanoma progression have not been investigated in this model. OBJECTIVE: The present study examined whether IH affects markers of melanoma tumor progression. METHODS: Mice were exposed to isocapnic IH to a nadir of 8% oxygen fraction for 14 days. One million B16F10 melanoma cells were injected subcutaneously. Immunohistochemistry staining for Ki-67, PCNA, S100-beta, HMB-45, Melan-A, TGF-beta, Caspase-1, and HIF-1alpha were quantified using Photoshop. RESULTS: Percentage of positive area stained was higher in IH than sham IH group for Caspase-1, Ki-67, PCNA, and Melan-A. The greater expression of several markers of tumor aggressiveness, including markers of ribosomal RNA transcription (Ki-67) and of DNA synthesis (PCNA), in mice exposed to isocapnic IH than in controls provide molecular evidence for a apnea-cancer relationship. CONCLUSIONS: These findings have potential repercussions in the understanding of differences in clinical course of tumors in obstructive sleep apnea patients. Further investigation is necessary to confirm mechanisms of these descriptive results.

Does nephrectomy during radical adrenalectomy for stage II adrenocortical cancer affect patient outcome?

PURPOSE: To evaluate if including nephrectomy in the standard surgical approach to stage II adrenocortical cancer (i.e., adrenalectomy) might modify oncologic outcome of patients. METHODS: We performed a retrospective analysis involving 41 patients with stage II adrenocortical cancer (ACC) who had undergone radical surgery. Patients were divided into two groups according to the surgical procedure: group A = radical adrenalectomy alone, group AN = radical adrenalectomy + radical nephrectomy. Oncologic effectiveness of the procedures was tested comparing the recurrence-free and overall survival of patients of A vs AN groups. RESULTS: The group A consisted of 25 patients and group AN of 16 patients. No differences were noted between the two groups in terms of demographic data and ACC characteristics. During follow-up, 15/25 (60 %) patients of group A vs 14/16 (87.5 %) patients of group AN experienced a recurrence, after a median of 36 months in group A and 10 months in group AN (p = 0.06); a significant impairment of renal function was recorded in patients of AN group with respect to those of group A. Finally, 13/25 (52 %) patients of group A and 10/16 (62.5 %) patients of group AN died due to ACC-related causes. No differences in survival times were noted (p = 0.3). CONCLUSION: Our study suggests that adjunctive nephrectomy does not modify the oncologic results of adrenalectomy in the treatment of stage II ACC in terms of recurrence-free and overall survival. Thus, when there are no signs of ACC local invasion, surgeon should make every effort to preserve the kidney.

Do malignant diseases affect semen quality? Sperm parameters of men with cancers.

The advent of modern treatments together with the improvement of the surgical techniques has significantly increased 5-year survival rates of young patients with cancer. Although the deleterious effects of chemotherapy and radiation are well documented, controversies exist about the effect of cancer itself on semen parameters before treatment. We collected data on 236 patients representative of different types of cancers reoffered at our institution for sperm cryopreservation with the aim to correlate the pre-freeze semen parameters with type of cancer, disease stage and with semen quality of 102 fertile and healthy men. The median baseline semen parameters of all our patients with cancer are placed above the 5th percentile of the World Health Organization reference value, but the type of cancer may impact the sperm parameters. In testicular tumours and in Hodgkin lymphoma, we show a semen concentration statistically lower than in the fertile population, while in patients with other cancers, there is no difference with the healthy men. We found no correlation between semen quality and disease stage. Eighty-six per cent of our patients do not have children at the time of semen cryopreservation, and the only established clinical option for preserving fertility of these men is cryopreservation of spermatozoa.

Robot-assisted radical prostatectomy: recent advances.

Robot assisted radical prostatectomy (RARP) represents the leading application of robotic surgery in the urologic field and it has become the main treatment option for localized prostate cancer (PCa) in the USA In the present review we summarized and critically analyzed the literature of the past five years about this widely used robotic procedure. RARP has continuously evolved in terms of technical modifications and procedural steps. Long-term data are now available, suggesting comparable oncological outcomes to those of open and laparoscopic radical prostatectomy. Good functional outcomes have also been demonstrated. Technological innovations and the introduction of more advanced robotic platforms featuring novel arm-integrated equipment, together with a mature clinical experience with the robotic approach, are likely to lead towards optimal outcomes. Despite the expanding clinical implementation of RARP in the management of prostate cancer, some issues related to this procedure remain matter of debate, such as costs, comparative outcomes versus other approaches, and its role in high risk disease.

A snapshot of nephron-sparing surgery in Italy: a prospective, multicenter report on clinical and perioperative outcomes (the RECORd 1 project).

INTRODUCTION: Nephron-sparing surgery (NSS) has become the standard of care for the surgical management of small and clinically localized renal cell carcinoma (RCC). The conservative management of those RCCs is increasing over time. Aim of this study was to report a snapshot of the clinical, perioperative and oncological results after NSS for RCC in Italy. MATERIAL AND METHODS: We evaluated all patients who underwent conservative surgical treatment for renal tumours between January 2009 and December 2012 at 19 urological Italian Centers (RECORd project). Perioperative, radiological and histopathological data were recorded. Surgical eras (2009 vs 2012 and year periods 2009-2010 vs 2011-2012) were compared. RESULTS: Globally, 983 patients were evaluated. More recently, patients undergoing NSS were found to be significantly younger (p = 0.05) than those surgically treated in the first study period, with a significantly higher rate of NSS with relative and imperative indication (p < 0.001). More recently, a higher percentage of procedures for cT1b or cT2 renal tumours was observed (p = 0.02). Utilization rate of open partial nephrectomy (OPN) constantly decreased during years, laparoscopic partial nephrectomy (LPN) remained almost constant while robot-assisted partial nephrectomy (RAPN) increased. The rate of clampless NSS constantly increased over time. The use of at least one haemostatic agent has been significantly more adopted in the most recent surgical era (p < 0.001). CONCLUSIONS: The utilization rate of NSS in Italy is increasing, even in elective and more complex cases. RAPN has been progressively adopted, as well as the intraoperative utilization of haemostatic agents and the rate of clampless procedures.

Effect of myo-inositol and alpha-lipoic acid on oocyte quality in polycystic ovary syndrome non-obese women undergoing in vitro fertilization: a pilot study.

The aim of the present study was to evaluate the effectiveness of the combined administration of myo-inositol and α-lipoic acid in polycystic ovary syndrome (PCOS) patients with normal body mass index (BMI), who had previously undergone intracytoplasmic sperm injection (ICSI) and received myo-inositol alone. Thirty-six of 65 normal-weight patients affected by PCOS who did not achieve pregnancy and one patient who had a spontaneous abortion were re-enrolled and given a cycle of treatment with myo-inositol and α-lipoic acid. For all female partners of the treated couples, the endocrine-metabolic and ultrasound parameters, ovarian volume, oocyte and embryo quality, and pregnancy rates were assessed before and after three months of treatment and compared with those of previous in vitro fertilization (IVF) cycle(s). After supplementation of myo-inositol with α-lipoic acid, insulin levels, BMI and ovarian volume were significantly reduced compared with myo-inositol alone. No differences were found in the fertilization and cleavage rate or in the mean number of transferred embryos between the two different treatments, whereas the number of grade 1 embryos was significantly increased, with a significant reduction in the number of grade 2 embryos treated with myo-inositol plus α-lipoic acid. Clinical pregnancy was not significantly different with a trend for a higher percentage for of myo-inositol and α-lipoic acid compared to the myo-inositol alone group. Our preliminary data suggest that the supplementation of myo-inositol and α-lipoic acid in PCOS patients undergoing an IVF cycle can help to improve their reproductive outcome and also their metabolic profiles, opening potential for their use in long-term prevention of PCOS.

Simple enucleation versus standard partial nephrectomy for clinical T1 renal masses: perioperative outcomes based on a matched-pair comparison of 396 patients (RECORd project).

OBJECTIVES: To compare simple enucleation (SE) and standard partial nephrectomy (SPN) in terms of surgical results in a multicenter dataset (RECORd Project). MATERIALS AND METHODS: patients treated with nephron sparing surgery (NSS) for clinical T1 renal tumors between January 2009 and January 2011 were evaluated. Overall, 198 patients who underwent SE were retrospectively matched to 198 patients who underwent SPN. The SPN and SE groups were compared regarding intraoperative, early post-operative and pathologic outcome variables. Multivariable analysis was applied to analyze predictors of positive surgical margin (PSM) status. RESULTS: SE was associated with similar WIT (18 vs 17.8 min), lower intraoperative blood loss (177 vs 221 cc, p = 0.02) and shorter operative time (121 vs 147 min; p < 0.0001). Surgical approach (laparoscopic vs. open), tumor size and type of indication (elective/relative vs absolute) were associated with WIT >20 min. The incidence of PSM was significantly lower in patients treated with SE (1.4% vs 6.9%; p = 0.02). At multivariable analysis, PSM was related to the surgical technique, with a 4.7-fold increased risk of PSM for SPN compared to SE. The incidence of overall, medical and surgical complications was similar between SE and SPN. CONCLUSIONS: Type of NSS technique (SE vs SPN) adopted has a negligible impact on WIT and postoperative morbidity but SE seems protective against PSM occurrence.

Effect of vardenafil on semen parameters in infertile men: a pilot study evaluating short-term treatment.

BACKGROUND: Severeal in vivo and in vitro studies have been carried out in order to evaluate the efficacy of long-term treatment with phosphodiesterase type-5 (PDE5) inhibitors (PDE5i) on spermatogenesis, but the results are still controversial. AIM: To evaluate the effects of vardenafil on seminal parameters of infertile men after a short-term treatment. MATERIALS/SUBJECTS AND METHODS: A total of 205 male subjects were randomized to receive a single dose of vardenafil 10 mg (73 men, group B), a single dose of vardenafil 10 mg every other day for 15 days (67 men, group C), and no treatment (65 men, group A). Semen parameters were evaluated before and after the end of the treatment in each of group A, B, and C, respectively. Additionally, an IIEF- 5 questionnaire was administered to all patients with erectile dysfunction (ED) before and after each treatment period. RESULTS: The semen parameters in groups B and C has shown a significant increase in percentage forward motility after vardenafil administration as compared with baseline (p<0.001). In group C, we observed an increase in the mean semen volume and an improvement in the mean total sperm concentration (p<0.001) as compared with baseline. CONCLUSIONS: We showed the efficacy of vardenafil in the treatment of ED and, on a large series of infertile patients, the positive effect on sperm motility after a single-dose administration. It also showed that after 15 days of treatment on alternate days is also achieved an improvement in sperm concentration.

Bilateral adrenalectomy for Cushing's syndrome: a comparison between laparoscopy and open surgery.

We report our experience with bilateral adrenalectomy for treatment of Cushing's syndrome and we compare the outcome of laparoscopy with open surgery in terms of effectiveness and safety. A series of 23 patients underwent bilateral adrenalectomy for treatment of Cushing's syndrome [Cushing's disease in 16, ectopic ACTH syndrome in 2, and ACTH-independent macronodular adrenal hyperplasia (AIMAH) in 5 cases]. From 1993 to 1996, all patients were treated using an open approach (Group A), while from 1997 all patients were treated using a transperitoneal laparoscopic approach (Group B). The comparison between the 2 groups was performed considering patients characteristics, operative times, blood losses, intraoperative and post-operative complications, analgesic consumption, post-operative hospital stay and recovery. Open surgery was performed in 10 patients and laparoscopy in 13 patients. No significant difference was recorded between the two groups as to patients' characteristics and complications. Mean operative time was significantly increased in Group B, while post-operative hospital stay was significantly longer in Group A. Laparoscopic bilateral adrenalectomy can be safely and effectively employed to treat Cushing's syndrome. However, long operatives times may represent a limitation especially in high risk patients.

Is laparoscopic bladder diverticulectomy after transurethral resection of the prostate safe and effective? Comparison with open surgery.

PURPOSE: In a retrospective nonrandomized study, we compared our experience with transurethral resection of the prostate (TURP) plus sequential laparoscopic bladder diverticulectomy with a series of combined open bladder diverticulectomies with transvesical prostatectomy. PATIENTS AND METHODS: We considered 12 consecutive patients (group A) having 16 diverticula who underwent sequential TURP and transperitoneal laparoscopic bladder diverticulectomy and 13 consecutive patients (group B) having 13 diverticula who underwent open bladder diverticulectomy and transvesical prostatectomy. We evaluated the size and position of the diverticulum, adenoma volume, operative time, postoperative hemoglobin variations, analgesia requirement, complications, postoperative hospital stay, and uroflowmetry results. RESULTS: No statistically significant differences existed between the groups in adenoma volume or diverticulum size or position. However, a significantly longer operative time was recorded in group A. The endolaparoscopic approach proved to be statistically superior to open surgery regarding blood loss, postoperative analgesia requirement, and hospital stay. No intraoperative complications were recorded. In addition, no statistically significant difference was found in uroflowmetry results. CONCLUSIONS: In our experience, the endolaparoscopic approach has proved to be safe, effective, and minimally invasive and therefore superior to transvesical prostatectomy and open bladder diverticulectomy. Its only disadvantage is the longer operative time.
