Background: Thanks to the improved accuracy of multiparametric Magnetic Resonance Imaging (mpMRI) to detect and localize the dominant index lesion on prostate cancer (PCa), the concept of minimally invasive focal treatments (FT) has gained popularity. Nevertheless, although high-quality evidence that FT has favorable functional outcomes, definitive proof of its oncological effectiveness compared to standard treatments remains underreported.

Objective: This study aims to explore the efficacy, safety, oncologic and functional outcomes of different type of FT for PCa.

Evidence acquisition: A non-systematic literature review was conducted by searching on PubMed "prostate cancer" AND "focal treatment" OR "HIFU" OR "irreversible electroporation" OR "cryoablation" OR "focal laser ablation." Overall, 22 articles published in English literature from 2018 to 2023 describing FT techniques for PCa were included.

Evidence synthesis: Related to the field ablated, focal therapies include hemiablation (half gland), focal ablation (zonal-base) or targeted therapy (lesion-based). FT modalities can be categorized in thermal and non-thermal energy: thermal energy techniques include high-intensity focused ultrasound (HIFU), cryotherapy, radiofrequency ablation (RFA), and focal laser ablation (FLA). Focal brachytherapy, irreversible electroporation (IRE), and vascular-targeted photodynamic therapy (VTP) are classified as non-thermal ablation. Each focal ablative treatments could be promising alternative to conventional radical therapies to treat PCa in term of mid-term oncologic and functional outcomes, however, limited data are available in comparison with standardized radical treatments. HIFU and Cryo are the most studied techniques and seem to be superior to radical treatments in term of functional outcomes despite associated with higher recurrence and retreatment rate.

Conclusions: Current evidences of oncologic and functional outcomes of FT are based mainly on retrospective, non-comparative and single center studies. Thus, none of the focal therapies available should be considered safe alternative to standardized treatments in routine practice and should be offered only for well selected PCa patients with low or at least favorable-intermediate risk disease, unfit for radical options.

Introduction: Benign prostatic hyperplasia (BPH) is a prevalent urological condition leading to lower urinary tract symptoms. Minimal invasive surgical treatment (MISTs) such as Rezūm System are emerging aiming to relieve symptoms. We present results from a single centre prospective study.

Methods: We prospectively followed patients undergoing Rezūm between 2021 and 2023 from a single centre. International Prostate Symptom Score (IPSS), functional outcomes (maximum urinary flow rate (Qmax) and post-void urinary residual (PVR) and International Index of Erectile Function-5 (IIEF-5) were assessed at 3, 6, 12 and 24 months. Anterograde ejaculation was assessed at 12 months follow up. Linear mixed-effects models (LMMs) for repeated measures were applied to assess differences in the IPSS, maximum flow rate (Qmax), PVR, and International Index of Erectile Function-5 (IIEF-5) from baseline (t0) to 3, 6, 12 and 24 months. Results: After adjusting for prostate volume and symptoms severity, significant differences were observed at 3, 6, 12 and 24 months for IPSS (p < 0.001), Qmax (p < 0.001), PVR (p < 0.001) and IPSS-QoL (p < 0.001) from baseline. No statistically significant changes were found in the IIEF-5 scores at 3, 6, 12 and 24 months from baseline. Anterograde ejaculation remained in 98% of patients after treatment.

Conclusions: In conclusion, the study's findings indicate that patients undergoing Rezūm treatment experience sustained improvements in IPSS, Qmax, PVR and IPSS-related quality of life up to 24 months following the intervention. Anterograde ejaculation remained in 98% of patients after treatment.

Objective: To evaluate the prevalence, risk factors, clinical manifestations, and outcomes of subcapsular renal hematoma (SRH) following ureterolithotripsy.

Patients and methods: Between January 2014 and December 2023, patients who underwent ureterorenoscopy lithotripsy (URL) at our hospital were retrospectively reviewed. Clinical data including basic information, calculi-related indicators, and perioperative period data were collected. A Student's t-test was used for continuous data, while a Chi-square test or Fisher's exact test was utilized for categorical data.

Results: A total of 2098 patients treated with URL for ureteric stones were included in this study. The incidence of SRH after URL was 0.52% (11 cases). All SRH cases were confirmed by non-contrast computed tomography, with an average patient age of 55.54 years (range 34-84). The mean stone size in patients with SRH was 10.54 cm (range 0.8-1.5). Patients with SRH had a higher proportion of severe hydronephrosis caused by ureteral stones (54.55% vs 26.07%, p = 0.032) and narrow ureters (45.45% vs 8.04%, p < 0.001) compared to those without SRH. Patients with SRH experienced a longer length of stay, with a significant difference between the two groups (11.64 ± 5.05 vs 3.87 ± 8.12, p < 0.001). Nine patients were managed conservatively without further intervention, while embolization was required in one patient and percutaneous drainage was performed in another. All SRH cases resolved completely during a 4-month follow-up.

Conclusions: The incidence of SRH following URL is low, with severe hydronephrosis and narrow ureters identified as risk factors. Most SRH cases can be successfully managed conservatively, although patients with SRH may experience a significant prolongation of their length of stay.

Sociocultural, the penis has represented an essential element in the identity and masculinity of Western men. Therefore, its injury, damage, or loss leads to psychosocial problems affecting these people's health and well-being. Penile cancer is a rare malignancy (it represents 1.44% of the cases of genitourinary cancers) that has direct effects on the genitals, and its treatment consists of penectomy (removal of the penis). The loss of the penis due to this disease has a profound impact on the survivors. It is associated with higher rates of depression, anxiety, and loss of male identity, some even feeling like "castrated animals" or fewer men, having not only biological but also social and psychological problems, leading to the loss or decrease of sexual activity, self-esteem, and ability to relate to others. The new masculinities (a social theory much discussed these days) is offered as an alternative to understanding the behavior of men concerning what represents the penis, and the construction of their identity, focusing on the need to reconstruct the idea of masculinity and unlink the identity of men outside their genitals, the discussion of such social elements can be offered alternatives to help improve the psychological condition of patients who have survived the penectomy and contribute significantly to their health and quality of life, especially in improving your mental health.

Objective: To assess the correlation between the general (gender, age, and maximum tumor size) and 3D morphotopometric features of the renal tumor node, following the MSCT data post-processing, and the tumor histological structure; to propose an equation allowing for kidney malignancy assessment based on general and morphometric features.

Materials and methods: In total, 304 patients with unilateral solitary renal neoplasms underwent laparoscopic (retroperitoneoscopic) or robotic partial or radical nephrectomy. Before the procedure, kidney contrast-enhanced MSCT followed by the tumor 3D-modeling was performed. 3D model of the kidney tumor, and its morphotopometric features, and histological structure were analyzed. The morphotopometric ones include the side of the lesion, location by segments, the surface where the tumor, the depth of the tumor invasion into the kidney, and the shape of tumor.

Results: Out of 304 patients, 254 (83.6%) had malignant kidney tumors and 50 (16.4%) benign kidney tumors. In total, 231 patients, out of 254 (90.9%) were assessed for the degree of malignant tumor differentiation. Malignant tumors were more frequent in men than in women (p < 0.001). Mushroom-shaped tumors were the most common shapes among benign renal masses (35.2%). The most common malignant kidney tumors had spherical with a partially uneven surface (27.6%), multinodular (tuberous (27.2%)), and spherical with a conical base (24.8%) shapes. Logistic regression model enabled the development of prognostic equation for tumor malignancy prediction ("low" or "high"). The univariate analysis revealed the correlation only between high differentiation (G1) and a spherical tumor with a conical base (p = 0.029).

Conclusion: The resulting logistic model, based on the analysis of such predictors as gender and form of kidney lesions, demonstrated a large share (87.6%) of correct predictions of the kidney tumor malignancy.

Background: Premature ejaculation (PE) is a common sexual problem, resulting in adverse effects on the quality of life, of both the patient and the partner. The idea of muscular contraction inhibition during the ejection phase of ejaculation by Botulinum toxin-A injection may delay ejaculation.

Aim of study: This study was performed to assess the efficacy and safety of Botulinum toxin-A injection in PE treatment.

Material and methods: This study included 45 married male patients diagnosed with primary PE. All included patients were injected with 75 units of Dysport equal efficacy of 25 units of Botulinum toxin-A (Botox) into three sites: the root of the penis (Group 1), glans penis (Group 2), and each side of the ischiocavernosus muscle (Group 3). All patients were subjected to an assessment of intravaginal ejaculation latency time (IELT) using a stopwatch and answering the Premature Ejaculation Diagnostic Tool (PEDT) Questionnaire before and after treatment.

Results: There was a statistically significant improvement in IELT after treatment in all groups. The most significant improvement was shown in Group 3 (average 108% increase), followed by Group 1 (74%) and Group 2 (40%), respectively. There was a positive correlation between age and the improvement in improved IELT. There was a statistically significant improvement in PEDTq scores in Group 1 and Group 3.

Conclusion: Botulinum toxin-A injection into the root of the penis and ischiocavernosus muscle could be recommended in the treatment of premature ejaculation.

Introduction: Crystalluria is an important indicator of renal stone recurrence. Mechanisms underlying urinary stone formation are still not fully understood and raising interests has been giving to intestinal commensal bacteria for their contribute in maintaining urinary solutes equilibrium. The aim of our phase II study was to examine the administration of potassium citrate, magnesium and probiotics in order to reduce crystalluria.

Materials and methods: Since May 2021, we enrolled 23 patients candidates for ureterorenolithotripsy for calcium oxalate kidney stones with crystalluria and a normal metabolic profile. The analysis was validated by the Institution's Ethical Committee (no. approval STS CE Lazio 1/N-823). At discharge, patients were provided with daily food supplementation for 20 days of 1 billion Lactobacillus paracasei LPC09, 1 billion Lactobacillus plantarum LP01, 1 billion Bifidobacterium breve BR03, potassium (520 mg), citrate (1400 mg), and magnesium (80 mg). Crystalluria was re-assessed at 1, 3, 6, and 12-months follow-up by polarized light microscopy.

Results: After one month from the oral supplementation, no patient reported crystalluria; at 3 months, among the 20 participants available for re-evaluation, still no patient reported crystalluria. Instead, crystalluria was reported in three patients (15%) at 6 months, and in five patients (25%) at 12 months follow-up.

Conclusions: The oral supplementation with Lactobacillus spp. and Bifidobacterium spp. was found able to reduce the prevalence of crystalluria in a cohort of patients with diagnosis of calcium oxalate kidney stones with crystalluria candidate to ureterorenolithotripsy.

Background: This study aimed to evaluate the predictive values and relationships of serum prostate-specific antigen (PSA) levels, delta neutrophil index (DNI), neutrophil-lymphocyte ratio (NLR), and other hematological parameters in patients diagnosed with acute prostatitis.

Methods: Serum PSA levels and hemogram parameters of patients diagnosed with acute prostatitis were retrospectively analyzed. Healthy patients of the same age group were assigned to the control group. WBC, neutrophil, lymphocyte, thrombocyte (PLT), mean platelet volume (MPV), plateletcrit (PCT), NLR, and DNI were determined. Serum total PSA and C-reactive protein (CRP) levels were also assessed.

Results: Total PSA levels (3.48 [1.11-6.66]) in the acute prostatitis (AP) group were significantly higher than those of healthy men (0.82 [0.47-1.39]) (p < 0.001). Total CRP levels (3.88 [1.50-22.03]) in the AP group were significantly higher than those in healthy men (1.15 [0.89-2.00]) (p < 0.001). The sensitivity and specificity of PSA at a cutoff value of 1.52 were 68.4% and 79.7%, respectively. The NLR value in the AP group was 2.62 (1.87-4.42), compared to 1.63 (1.18-2.20) in the healthy group (p < 0.001). Differences in WBC, neutrophil, and lymphocyte counts were also statistically significant (p < 0.001). There were no significant differences in PLT, PCT, or DNI values. Significant positive correlations were observed between PSA, CRP, and DNI values (all p < 0.001).

Conclusion: This study demonstrated the usefulness of NLR, PSA, CRP, and WBC as predictors of acute prostatitis. NLR is a simple, inexpensive inflammation parameter that correlates well with CRP levels.

Social media (SoMe) is now a core part of modern-day life with increased use among both patients and urologists. The interplay of SoMe between these two parties is complex. From a patient perspective, SoMe platforms can serve as educational tools as well as communication portals to support networks and patient communities. However, studies report the educational value of content online is often poor and may contain misinformation. For urologists, SoMe can lead to research collaborations, networking and educational content but areas of concern include the potential negative impact SoMe can have on mental health and sharing of patient images without appropriate consent. This review serves to provide an overview of the interaction between SoMe and urology practice and provide practical guidance to navigating it.
