PurposeTo perform a systematic search and review of the available literature on the learning curves (LCs) in laparoscopic and robot-assisted prostate surgery.MethodsMedline was systematically searched from 1946 to January 2021 to detect all studies in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement, reporting on the LC in laparoscopic radical prostatectomy (LRP), laparoscopic simple prostatectomy (LSP), robot-assisted radical prostatectomy (RARP) and robot-assisted simple prostatectomy (RSP).ResultsIn total, 47 studies were included for qualitative synthesis evaluating a single technique (LRP, RARP, LSP, RSP; 45 studies) or two techniques (LRP and RARP; 2 studies). All studies evaluated outcomes on real patients. RARP was the most widely investigated technique (30 studies), followed by LRP (17 studies), LSP (1 study), and RSP (1 study). In LRP, the reported LC based on operative time; estimated blood loss; length of hospital stay; positive surgical margin; biochemical recurrence; overall complication rate; and urinary continence rate ranged 40–250, 80–250, 58–200, 50–350, 110–350, 55–250, 70–350 cases, respectively. In RARP, the corresponding ranges were 16–300, 20–300, 25–200, 50–400, 40–100, 20–250, 30–200, while LC for potency rates was 80–90 cases.ConclusionsThe definition of LC for laparoscopic and robot-assisted prostate surgery is not well defined with various metrics used among studies. Nevertheless, LCs appear to be steep and continuous. Implementation of training programs/standardization of the techniques is necessary to improve outcomes.

Background and Objectives: Vaginal vault prolapse is a known complication following anterior pelvic exenteration in women undergoing radical cystectomy. The aim of this study is to evaluate the feasibility, safety, and early outcomes of a novel anatomical approach for preventing vaginal vault prolapse after radical cystectomy. This study introduces a standardized laparoscopic technique that utilizes round ligament preservation and fixation to provide anatomical support to the vaginal apex. Materials and Methods: This study is a retrospective analysis of prospectively collected data from a single center, including thirteen female patients with uterus and adnexa in situ who underwent laparoscopic radical cystectomy with bilateral round ligament fixation to the vaginal cuff. The round ligaments were mobilized and sutured without tension. Vaginal closure was performed with barbed sutures. Results: No intraoperative complications occurred. At a median follow-up of 18.2 months, no cases of vaginal vault prolapse or dehiscence were observed. One patient experienced transient pelvic discomfort. Conclusions: This is the first report of a standardized mesh-free approach for vaginal apex support during laparoscopic anterior exenteration. The technique is feasible, safe, and may reduce postoperative prolapse risk.

Urinary incontinence (UI) is a bothersome symptom with population studies suggesting a prevalence of 13.1% in women and 5.4% in men. While a significant cohort of patients with this complaint may ultimately require surgical management to achieve complete continence, a number of non-surgical measures exist to improve symptoms and quality of life. A range of guidelines exist on this topic, including those published by the European Association of Urology (EAU), the International Continence Society (ICS), the American Urological Association (AUA) and the UK's National Institute for Health and Care Excellence (NICE). The aim of our study is to provide an overview of the initial assessment of patients with UI including history taking, examination and basic investigations. Our review outlines non-surgical management strategies for UI, including conservative measures, behavioral and physical therapies and drug treatment. We shall also examine the above guidelines and present a narrative overview of the literature surrounding the diagnosis and non-surgical management of urinary incontinence.

Multiple endocrine neoplasia (MEN) syndromes are rare and potentially malignant hereditary entities. Clinical manifestations of MEN 2B include medullary thyroid cancer, pheochromocytoma, gastrointestinal ganglioneuromatosis, and musculoskeletal and ophthalmologic lesions. Metastases to the prostate from the cancers of other organs are extremely rare. There are only a few cases of metastases to the prostate gland, originating from medullary thyroid cancer, found in literature, especially associated with MEN 2B syndrome. In this case report, we present the extremely rare case of a 28-year-old patient, diagnosed with MEN 2B syndrome, with medullary thyroid cancer metastasis to the prostate. Although a few reports of medullary thyroid cancer metastasis into the prostate gland can be found in the literature, to our knowledge, this is the first case of a laparoscopic radical prostatectomy procedure performed as a metastasectomy to treat the prostatic metastasis. Laparoscopic radical prostatectomy, performed as a metastasectomy, for the treatment of metastatic cancer, is an extremely rare surgical indication with distinctive requirements and difficulties. The extraperitoneal access enables the realization of the laparoscopic radical prostatectomy procedure even in the cases of patients with a history of multiple intra-abdominal operations.

Zinner's syndrome is a rare congenital disorder presenting with unilateral renal agenesis or dysgenesis, ipsilateral seminal vesicle cysts, and ejaculatory duct obstruction. Treatment of this syndrome can be conservative or surgical. In this case report, we describe the case of a 72-year-old patient who was diagnosed with Zinner's syndrome and underwent laparoscopic radical prostatectomy for prostate cancer treatment. The peculiarity of our case was that the patient's ureter emptied ectopically into the left seminal vesicle, which was notably enlarged and multicystic in appearance. Although many minimally invasive procedures have been reported for treating symptomatic Zinner's syndrome, to our knowledge, this is the first reported case of prostate cancer in a patient with Zinner's syndrome who was treated with laparoscopic radical prostatectomy. Laparoscopic radical prostatectomy can be safely and efficiently performed in patients with Zinner's syndrome and synchronous prostate cancer by urological surgeons with extensive experience in laparoscopy in high-volume centers.

Acute kidney injury (AKI) is associated with increased morbidity, prolonged hospitalization, and mortality, especially in high risk patients. Phosphodiesterase 5 inhibitors (PDE5Is), currently available as first-line therapy of erectile dysfunction in humans, have shown a beneficial potential of reno-protection through various reno-protective mechanisms. The aim of this work is to provide a comprehensive overview of the available literature on the reno-protective properties of PDE5Is in the various forms of AKI. Medline was systematically searched from 1946 to November 2019 to detect all relevant animal and human studies in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. In total, 83 studies were included for qualitative synthesis. Sildenafil is the most widely investigated compound (42 studies), followed by tadalafil (20 studies), icariin (10 studies), vardenafil (7 studies), zaprinast (4 studies), and udenafil (2 studies). Even though data are limited, especially in humans with inconclusive or negative results of only two clinically relevant studies available at present, the results of animal studies are promising. The reno-protective action of PDE5Is was evident in the vast majority of studies, independently of the AKI type and the agent applied. PDE5Is appear to improve the renal functional/histopathological alternations of AKI through various mechanisms, mainly by affecting regional hemodynamics, cell expression, and mitochondrial response to oxidative stress and inflammation.

PurposeRecurrent urinary retention due to benign prostate hyperplasia (BPH), requiring permanent catheterization, represents one of the most challenging issues geriatric patients can face. Rezūm, as a minimal invasive treatment for BPH, takes the advantage of sterile water vapor injections directly into the prostate. The purpose of this Systematic Review is to report the safety and the efficacy of Rezūm regarding urinary retention relief and permanent catheter withdrawal. MethodsPubMed, Scopus and Cochrane databases were meticulously screened using the keywords “Rezum”, “retention” and “permanent catheter”. Only human studies and articles in English were included. Rezūm should be the only intervention employed in patients. Patients of included studies should not have been submitted to any prior interventions, such as transurethral prostatectomy (TURP) for the relief of their symptoms. Patients’ baseline characteristics along with intraoperative and postoperative parameters were collected and analysed. Catheter relief was the primary outcome.ResultsFive studies fulfilled all the criteria and were included in the final qualitative synthesis. Four studies were retrospective and one was prospective. All studies were non-comparative. The success rate ranged from 70.3 to 100%, while no grade ≥ III Clavien–Dindo complications were reported in any of the studies. ConclusionRezūm Water Vapor Therapy Treatment seems to be a feasible, safe and efficient minimally-invasive procedure for catheterized patients with urinary retention secondary to BPH, especially for frail ones with comorbidities who cannot undergo general anesthesia.

Objectives: Since tumor focality in prostate cancer continues to be considered a major limitation for focal prostate therapy, in this study we attempted to compare the pathological features and the proportion of patients with anatomically unifocal versus biologically unifocal tumors (i.e. multifocal prostate cancer in which the secondary nonindex elements are small, low grade and clinically insignificant) who were suitable for focal therapy. Methods: Ninety-five consecutive whole mount laparoscopic radical prostatectomy samples underwent pathological assessment (from January 2007 to November 2009). Tumor focality, laterality, Gleason score and volume of individual foci, total tumor volume, pathological stage and surgical margin status were assessed. The index lesion was defined as the largest by volume. Patients suitable for focal ablation were defined as having tumors that were unifocal, organ confined, with a Gleason score (GS) up to 7 prostate cancer, or multifocal, organ confined, GS up to 7 prostate cancer, with one large index lesion and the remaining foci demonstrating features of clinically insignificant disease (total tumor volume of all secondary foci ≤0.5 cm3 with GS ≤ 6). Results: Patients with biologically unifocal cancer had significantly lower total tumor volume (3.26 versus 7.28 cm3; p < 0.001), index lesion volume (2.9 versus 7.16 cm3; p < 0.001), rates of seminal vesicle invasion (4% versus 34%; p < 0.001), rates of positive surgical margins (22.4% versus 52.1%; p < 0.001) and rates of 4+3 GS tumors (10.2% versus 29.1%; p = 0.018). The proportion of patients suitable for focal therapy was higher in the biologically unifocal versus anatomically unifocal cancer group, although without reaching statistical significance (65.3% versus 45.8%; p = 0.11). Conclusions: Patients with biologically unifocal tumors have better pathological outcome than those with anatomically unifocal disease. At present the assumption that multifocality should a priori exclude patients from any organ-preserving prostate cancer treatment is only theoretical and needs to be validated by future clinical trials since there are a large proportion of patients with multifocal disease apparently suitable for focal prostate therapy.

PurposeShockwave lithotripsy (SWL) is a minimally invasive technique utilized for renal and ureteric stones in children. Despite being considered safe, certain complications have been recorded. We performed this systematic review and meta-analysis to provide a pooled analysis of Clavien–Dindo graded complications after SWL in children.MethodsMEDLINE/PubMed, Scopus and Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews, were screened from inception to 12/02/2022 by two authors independently. Only randomized controlled trials providing Clavien–Dindo classification or relevant clinical information were considered eligible. Overall complications were calculated using the aggregate number of each complication divided by the total number of patients in studies with data.ResultsPooled analysis revealed that from children treated with SWL, 27.7% [95% CI 13.1–49.4] suffered Clavien I complications, 4.9% [95% CI 3.1–7.6] Clavien II complications, 2.7% [95% CI 1.6–4.7] Clavien III complications, 2.3% [95% CI 1.3–4] Clavien IV complications, while no Clavien V complications were recorded. In total, 28.1% [95% CI 15.6–45.3] of children suffered minor complications (Clavien–Dindo I–II), while 3% [95% CI 1.8–5] major complications (Clavien–Dindo III–V). Pooled analysis revealed that 10.7% [95% CI 3.2–30.1] of patients suffered macroscopic hematuria, 7.3% [95% CI 2.1–22.7] pain, 5.5% [95% CI 3.3–9] steinstrasse, 5.3% [95% CI 3–9.3] fever, 2.2% [95% CI 0.8–5.6] sepsis, 1.1% [95% CI 0.3–3.7] urinoma, 1% [95% CI 0.4–2.7] symptomatic hematoma and 1% [95% CI 0.3–2.7] asymptomatic hematoma. Need for re-treatment was 42.6% [95% CI 31.4–54.7] and need for auxiliary procedures was 11.8% [95% CI 8.5–16.1].ConclusionSWL is an irreplaceable tool for treating urolithiasis in children. Although a minimally invasive technique, parents and children should be adequately informed about the risk of minor/major complications.
