Comparison Study between Artificial Urinary Sphincter and Adjustable Male Sling: A Propensity-Score-Matched Analysis.

AIMS: This study aimed to compare the outcomes of the AUS and an adjustable male sling (ATOMSTM). METHODS: It was a retrospective observational cohort study with two arms. Propensity score matching (PSM) was performed in order to limit selection bias and, consequently, a comparison between groups in terms of functional outcomes (24 h pad test and perception of improvement questionnaires), complications (overall complications, high-grade complications, reinterventions and explantations) and device survival was performed. RESULTS: 49 patients in both arms were included. The baseline characteristics were similar between the groups. The mean follow up was 43 ± 35 months. Dryness was achieved in 22 patients (44.9%) in the AUS group and 11 (22.5%) in the sling group (p = 0.03). A total of 40 patients declared themselves well improved in the sling group (81%), while 35 (71%) declared the same in the AUS group (p = 0.78). The AUS was associated with more high-grade complications, reinterventions and explantations than the ATOMSTM. Survival at 60 months was 82 ± 9% in the sling group and 67 ± 7% in the AUS group (p = 0.03). CONCLUSIONS: While the AUS may be characterized by a higher dry rate, it has an increased risk of high-grade complications and reinterventions. It is proposed that the ATOMS prosthesis can be successfully used for patients who require a less invasive procedure that maintains good functional outcomes.

Infection Rate of a Prolonged Sacral Neuromodulation Test: A Large Retrospective Study.

OBJECTIVES: It is estimated that 3.8% to 12.5% of patients develop a device infection during the two to four weeks of the sacral neuromodulation (SNM) test, leading to removal of the entire system. It is possible to prolong the test phase up to the clinician's decision, particularly when benefits are unclear. The aim of our study is to assess the device infection rate in a prolonged SNM test. MATERIALS AND METHODS: We retrospectively enrolled patients who performed a prolonged SNM test (at least eight weeks) in the last five years (2017-2021). All procedures were performed using a standardized technique and the same prophylactic antibiotic protocol. In case of a clinical suspicion of infection, all components were explanted. Patient information (age at implantation, medical history of diabetes, metabolic syndrome, immunologic diseases, or chronic immunosuppressive therapy), surgical data (operative time, intraoperative complications), and infection data (timing of onset, symptoms reported, wound culture results) were recorded. RESULTS: We enrolled 232 patients who underwent a prolonged SNM test (mean duration 65.5 days). A local infection that led to the removal of the entire system occurred in six patients (2.6%). The gluteal pocket was always involved, and in two cases, infection was also extended to the exit point of the extension wire. No significant correlations with clinical data were found. Infection occurred beyond four weeks in two cases, between three and four weeks in three cases, and within two weeks in one case. Intraoperative wound culture was performed in five of six patients, and Staphylococcus aureus (S aureus) was isolated in four cases. One culture test gave negative bacterial growth results. CONCLUSIONS: The infection rate of a prolonged eight-week SNM test is low and does not differ from that reported in the literature for a two-to-four-week SNM test. S aureus remains the most frequent bacterium involved.

Robotic Radical Prostatectomy for Prostate Cancer in Renal Transplant Recipients: Results from a Multicenter Series.

BACKGROUND: Despite an expected increase in prostate cancer (PCa) incidence in the renal transplant recipient (RTR) population in the near future, robot-assisted radical prostatectomy (RARP) in these patients has been poorly detailed. It is not well understood whether results are comparable to RARP in the non-RTR setting. OBJECTIVE: To describe the surgical technique for RARP in RTR and report results from our multi-institutional experience. DESIGN, SETTING, AND PARTICIPANTS: This was a retrospective review of the experience of four referral centers. SURGICAL PROCEDURE: Transperitoneal RARP with pelvic lymph node dissection in selected patients. MEASUREMENTS: We measured patient, PCa, and graft baseline features; intraoperative and postoperative parameters; complications, (Clavien classification); and oncological and functional outcomes. RESULTS AND LIMITATIONS: We included 41 men. The median age, American Society of Anesthesiologists score, preoperative renal function, and prostate-specific antigen were 60 yr (interquartile range [IQR] 57-64), 2 points (IQR 2-3), 45 ml/min (IQR 30-62), and 6.5 ng/ml (IQR 5.2-10.2), respectively. Four men (9.8%) had a biopsy Gleason score >7. The majority of the patients (70.7%) did not undergo lymphadenectomy. The median operating time, hospital stay, and catheterization time were 201 min (IQR 170-250), 4 d (IQR 2-6), and 10 d (IQR 7-13), respectively. At final pathology, 11 men had extraprostatic extension and seven had positive surgical margins. At median follow-up of 42 mo (IQR 24-65), four men had biochemical recurrence, including one case of local PCa persistence and one local recurrence. No metastases were recorded while two patients died from non-PCa-related causes. Continence was preserved in 86.1% (p not applicable) and erections in 64.7% (p = 0.0633) of those who were continent/potent before the procedure. Renal function remained unchanged (p = 0.08). No intraoperative complications and one major (Clavien 3a) complication were recorded. CONCLUSIONS: RARP in RTR is safe and feasible. Overall, operative, oncological, and functional outcomes are comparable to those described for the non-RTR setting, with graft injury remaining undescribed. Further research is needed to confirm our findings. PATIENT SUMMARY: Robot-assisted removal of the prostate is safe and feasible in patients who have a kidney transplant. Cancer control, urinary and sexual function results, and surgical complications seem to be similar to those for patients without a transplant, but further research is needed.

Natural history of widespread high grade prostatic intraepithelial neoplasia and atypical small acinar proliferation: should we rebiopsy them all?

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.

Do you really want to deactivate your sacral neuromodulation device during pregnancy? A single center case series.

INTRODUCTION AND HYPOTHESIS: The main objective of the study is to assess the efficacy and safety of sacral neuromodulation (SNM) during pregnancy. METHODS: We retrospectively enrolled patients who underwent SNM implantation in our center and subsequently became pregnant. The indication for SNM, timing of device de-activation (if performed), course of pregnancy and urological complications, duration of labor, childbirth term, delivery mode, congenital abnormalities and SNM dysfunctions after delivery were recorded. RESULTS: Fourteen pregnancies were recorded among 11 women undergoing SNM. Indications for device implantation were urinary retention (7 cases) and dysfunctional voiding (4 cases). Two patients carried on two and three pregnancies, respectively, with the device turned off since the first trimester. They both had to return to self-catheterization and developed recurring urinary tract infections. No major urological complications were recorded among the remaining nine women that kept the device on during pregnancy. A cesarean section was performed in four cases for obstetric reasons, and in seven cases it was planned by the urologist and gynecologist to avoid lead damage/displacement. Three pregnancies resulted in a vaginal delivery, and no association with term of delivery or duration of labor was observed. No congenital abnormalities related to SNM or lead displacement are reported, and only one patient required device removal because of significant loss of efficacy after childbirth. CONCLUSIONS: The use of SNM during pregnancy appears to be safe, without morbidity for the fetus. Moreover, risks associated with switching the device off may be greater than benefits and justify maintaining the electrical stimulation throughout pregnancy.

Sacral neuromodulation to treat voiding dysfunction in patients with previous pelvic surgery for deep infiltrating endometriosis: our centre's experience.

INTRODUCTION AND HYPOTHESIS: Voiding symptoms/dysfunctions (VS/Ds) after surgery for deep-infiltrating endometriosis (DIE) are frequent (20% of patients) and, together with bowel dysfunctions, may represent a de novo disorder due to surgical damage of the pelvic plexus or a worsening of pre-existent functional damage. Sacral neuromodulation (SNM) might improve voiding symptoms by treating dysfunctional voiding. The aim of this study is to report our experience with SNM in patients treated with surgery for DIE. METHODS: We retrospectively enrolled 13 patients with VS/Ds after surgery for DIE. All patients were investigated with urodynamic studies (UDS) and agreed to undergo SNM. Pre-existing VS/Ds, bowel disorders and pelvic pain, DIE surgical procedures, UDS and SNM test results were recorded. RESULTS: After surgery for DIE, functional bladder outflow obstruction and detrusor acontractility were observed in nine and four patients, respectively. Chronic pelvic pain was present in seven cases. Twelve patients developed constipation, whilst one patient had de novo faecal incontinence. After the SNM testing period, nine patients (69.2%) experienced a significant improvement of symptoms that led to definitive implant. Four patients (30.8%) had no symptom relief and the system was removed. CONCLUSIONS: Functional bladder outflow obstruction and urinary retention are the most common VS/Ds after surgery for DIE. SNM may be an effective option for these patients, probably due to its action in improving the dysfunctional voiding, which was likely to be already present as part of the "endometriotic syndrome" and got worse after pelvic surgery. Results for pelvic pain control and gastrointestinal disorders should not be underestimated.

The association of Boswellia resin extract and propolis derived polyphenols can improve quality of life in patients affected by prostatitis-like symptoms.

OBJECTIVES: Chronic prostatitis syndrome is a bothering and poorly understood condition. Many patients report genitourinary pain and Lower Urinary Tract Symptoms as a main complaint. Many different pharmacological or behavioural therapies are prescribed in daily clinical practice, but efficacy data are still lacking. The aim of our study was to test the efficacy and safety of a transrectal delivered association of Boswellia resin extract and propolis derived polyphenols for the relief of prostatitis - like symptoms. MATERIALS AND METHODS: Patients affected by chronic/recurrent prostatitis - like symptoms were prospectively enrolled in our study from December, 2016 to December, 2018. Patients were screened at baseline through clinical examination and validated questionnaires administration: Chronic Prostatitis Symptom Index (CPSI), International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF). Inclusion criteria were: age ≥ 18; prostatitis symptoms persisting for at least 3 of the last 6 months; CPSI pain domain score ≥ 5; previous negative Meares-Stamey test. Treatment consisted on the administration of 1 suppository containing Boswellia resin extract and propolis derived polyphenols, once a day for 20 days. The primary endpoint of the study was the improvement of quality of life after treatment, defined by a reduction of ≥ 2 points, or ≥ 25%, of mean CPSI pain domain score, compared to baseline. Secondary endpoints were the improvement of post-treatment CPSI total score and the analysis of treatment - related adverse events. All patients were re-evaluated 1 month after treatment. RESULTS: 40 patients were enrolled in our study. Median age (Inter - Quartile Range IQR) was 51.5 (41.5-63.2) years. Mean baseline CPSI scores were: 22.15 (total score), 9.67 (pain domain), 5.15 (micturition domain) and 7.35 (quality of life domain), respectively. No significant adverse events were reported. At 1 month follow-up, CPSI scores appeared modified as follows: 16.40 (total score, p = 0.001); 6.92 (pain domain; p = 0.001; 4.02 (micturition domain, p = 0.09); 5.45 (quality of life domain, p = 0.002). Mean CPSI pain domain score reduction was -2.75 points (-28.5%). Mean CPSI total score reduction was -5.75 points (-26%). CONCLUSIONS: The association of Boswellia resin extract and propolis derived polyphenols can reduce genitourinary pain and then improve quality of life of men affected by bothersome prostatitis - like symptoms.

Prostate cancer treatment in renal transplant recipients: a systematic review.

The aim of this review was to summarize the current evidence and to highlight the main issues future research needs to address regarding prostate cancer (PCa) treatment in renal transpant recipients (RTRs). We conducted a search of AMED, Medline and Embase up to 17 November 2016 to investigate oncological and functional outcomes of PCa treatment in RTR. Type and use/protocols of immunosuppression and peri-operative antibiotic drugs were also assessed. The search was implemented manually. Exclusion criteria were absence of full text or absence of information that allowed us to differentiate oncological and/or functional outcomes of each therapeutic approach used. We included 241 patients from 27 retrospective studies published between 1991 and 2016; seven of the studies were case-control and 20 were case series. We also considered nine case reports published between 1999 and 2016. Follow-up ranged from 1 to 120 months. PCa was organ-confined, with Gleason score ≤6 in 75.2% and 60.4% of patients. Surgery was the most frequent treatment used (n = 186), for which cancer-specific (CSS) and overall survival (OS) rates were both 96.8%. Functional outcomes, including continence and erectile function, and complications were less frequently reported and were generally similar to those reported for radical prostatectomy (RP) in non-RTRs. Other treatment methods in the patients included in the review were radiotherapy (RT) ± androgen deprivation therapy (ADT; n = 34; OS 88.2%; CSS 88.2%), ADT alone (n = 14; OS 42.9%; CSS 64.3%), brachytherapy (BT; n = 11; OS and CSS 100%), watchful waiting (n = 4) and active surveillance (n = 1). Overall no treatment-related graft loss occurred. Immunosuppression and antibiotic schemes were poorly reported and inconsistent. Outcomes of PCa treatment in RTRs are encouraging and do not appear to be inferior to those of non-RTR. RP was the most commonly assessed approach, whilst RT, BT and ADT were less frequent. Immunosuppression and antibiotic use were poorly reported and highly variable. High-quality studies are needed because the current level of evidence is low, and our results should therefore be interpreted with caution.

Receptor-based virtual screening evaluation for the identification of estrogen receptor ß ligands.

In this paper, a receptor-based virtual screening study for the identification of estrogen receptor ß (ERß) ligands was developed. Starting from a commercial database of 400,000 molecules, only six compounds resulted to be potential active ligands of ERß. Interestingly, all the six molecules possess scaffolds that had already been reported in known ERß ligands. Therefore, the results obtained herein confirm the reliability of our virtual screening procedure, thus encouraging the application of this protocol to larger commercial databases in order to identify new ERß ligands.
