Dear Editor, We read with interest the recently published article by Farci et al., titled "An unusual 'linitis plastica' like breast cancer bladder metastasis" and we congratulate the authors for the very interesting topic and case presented...

Objectives: To determine if histological evaluation of the vasa is useful when post-vasectomy semen analysis (PVSA) compliance is low and to determine whether compliance could be predicted.

Methods: A retrospective evaluation of patients undergoing vasectomy between 2018 and 2022 was undertaken. A comparison of the PVSA between three vasa histological categorisations was made: complete divisions, incomplete division(s), absent vas(a). A multivariate model was constructed to predict PVSA compliance.

Results: From 388 patients, 191 (49.2%) undertook PVSA. Four patients had a revision of vasectomy. On 3 occasions this was due to the histology findings and once from semen analysis with normal histology. There was no significant difference in the number of azoospermic samples (95.4% vs 91.2%, ns), of samples with presence of Rare Non-Motile Sperm (RNMS) (2.6% vs 8.8%, ns) and those with sperm present (2.0 vs 0%, ns), between patients with complete division of the vasa on both sides and those with incomplete division on one side respectively. There was no difference in patient characteristics between those who complied with PVSA and those who did not.

Conclusions: This paper suggests that there is a role for histological evaluation of the vasa when PVSA compliance is poor. Incompletely divided vasa on histology are not associated with an adverse PVSA.

Purpose: Our objective was to investigate the association between programmed death-ligand (PD-L1) immunoexpression measured as a combined positive score and clinical outcomes in penile SqCC.

Materials and methods: We retrospectively reviewed all penile SqCC cases diagnosed in our institution between 2018 and 2023. PD-L1 immunohistochemistry was performed as a qualitative assay. Immunoexpression in both tumor and immune cells equal or superior to 1 was considered positive.

Results: A total of 34 patients with conventional penile SqCC were included. Eleven cases were HPV-associated (32.4%). Twelve cases were PD-L1 CPS < 1 and twenty-two were PD-L1 CPS ≥ 1. Nine cases (32.4%) were PD-L1 CPS ≥ 1 and p16 positive, but this did not translate in worse clinicopathological features. Larger tumors (3.0 cm in PD-L1 CPS ≥ 1 vs 2.5 cm in PD-L1 CPS < 1; p = 0.662), vascular invasion (36.4% in PD-L1 CPS ≥ 1 vs. 25.0% in PD-L1 CPS < 1; p = 0.705) and perineural invasion (40.9% in PD-L1 CPS≥1 vs. 16.7% in PD-L1 CPS < 1; p = 0.252) were associated with PD-L1 expression. Among the high-risk features, only lymph node involvement had statistical significance, with 14 out of 22 PD-L1 CPS ≥ 1 patients (63.6%) having lymph node metastases when lymphadenectomy was performed (p = 0.031). With a median follow-up of 16 months (IQR 27.5), PD-L1 CPS ≥ 1 patients had worse overall survival (53.4 months vs 75.9 months), but no statistical significance could be inferred (p = 0.188).

Conclusions: It is noteworthy the clinical significance of lymph node involvement in PD-L1 CPS ≥ 1 cases and a trend towards worse overall survival in this group of patients.

Background: B-mode ultrasound (US) medical imaging is very effective in localizing and describing Peyronie's disease (PD). Moreover, elastography is a new technique used to evaluate tissue elasticity to detect penile Peyronie's plaques that are not visible using standard B-mode US.

Objective: The main objective of this study was to evaluate the diagnostic efficacy of real-time elastography (RTE) in PD patients and to determine whether its combined use with standard US improved diagnostic accuracy. RTE is also known as strain elastography (SE). Additionally, this study aimed to assess whether RTE was useful for monitoring PD patients undergoing conservative treatment.

Methods: A group of 37 PD patients in the active phase was selected based on US examination showing isoechoic or hypo-isoechoic plaques, with or without associated hyperechoic or calcified plaque areas. All patients underwent traditional US combined with RTE before starting conservative treatment with antioxidants, during treatment and after treatment. After each examination with RTE, a specific "Strain Ratio"(SR) was used to identify the specific elasticity of the tissue.

Results: Using B-mode US with RTE, we detected all 13 non-palpable penile plaques present in the 37 PD patients (100% of cases). Using only B-mode US, we detected only 8 of the 13 non-palpable plaques (61.5% of cases). The DI of the plaque decreased during and after treatment in all cases, indicating that RTE is effective for monitoring conservative PD treatment. A statistically significant correlation was found between the DI and plaque volume in all patients (p=0.002).

Conclusion: Our study has shown that the combination of US and RTE methods allowed for a more accurate diagnosis in PD patients.

Objective: Penoscrotal transposition (PST) is a rare anomaly of the external genitalia characterized by malposition of the penis in relation to the scrotum. This transposition may be partial or complete and may be associated with hypospadias, chordee, and other anomalies. We have reviewed our experience with the surgical repair of PST utilizing a modified Glenn-Anderson technique.

Materials and methods: Twenty-nine patients with a median age of 5.6 years (8 months -15 years) underwent surgical repair of PST at our institution between 2004-2022. Of those, 20 (69%) had complete PST, while 9 (31%) had partial PST. All children were divided into three groups. In the first group of 8 (28%) children, repair of PST was an integral part of one-stage male genitoplasty; in the second group of 18 (62%) children, repair of PST was an isolated last stage of the staged hypospadias repair and the remaining 3 (10%) children underwent PST repair without the presence of hypospadias. All patients underwent modification of the Glenn-Anderson technique involving utilization of bilateral rotational advancement scrotal flap, complete de-tethering of the testis from the internal part of the scrotum when indicated, and relocation of the scrotal compartment in a normal dependent position. The follow-up ranged from 6 months to 18 years.

Results: In the first group, five children (62%) underwent Onlay Prepucial Island Pedicle Flap (OIF) hypospadias repair, and three (38%) underwent Long Tubularized Incised Plate Repair (TIP). In the second group, 8 (44%) underwent OIF hypospadias repair, 2 (12%) had Long TIP repair, and the remaining 8 (44%) underwent staged hypospadias repair. Post-operative Clavien Dindo grade III presented among three patients in group I and only one patient in group II. In the third group, no postoperative complications were observed.

Conclusion: Our data show that penoscrotal transposition correction utilizing the Glenn-Anderson technique is a reliable and durable surgery in the pediatric population. These children require careful monitoring till adolescence to ensure that no re-operation is needed.

Introduction: The third most prevalent malignant neoplasm involving the urinary tract is renal cell carcinoma (RCC), encompassing nearly 3.5% of the entire cancers afflicting the body. The aim of this research was to explore how the R.E.N.A.L. nephrometry score relates to the decisions made regarding surgery in individuals with localized RCC.

Methods: This prospective study, assessed patients with localized parenchymal renal masses (stages I and II) tentatively diagnosed as RCC. Utilizing preoperative multiphasic renal CT scans and MRI, the R.E.N.A.L. score categorized masses for nephrometry values. Inclusion criteria involved collecting patient data, and data collection utilizing a structured format focusing on the nephrometry grading system.

Results: The study included 64 patients aged (mean ± SD) 49.78 ± 12.35 yrs. Undergoing renal mass surgery, there were 17 (26.5%) low, 28 (43.8%) moderate and 19 (29.7%) high-complexity lesions. All patients with a low Nephrometry score (n = 17) underwent partial nephrectomy, and all cases with a high score (n = 19) underwent radical nephrectomy. For those with a moderate Nephrometry score (n = 28), 13 (46.4%) underwent partial nephrectomy, while the remaining 15 (53.6%) cases underwent radical nephrectomy. Morbidity was low, and no mortality occurred at 180 days. Patients who had lesions fully above or below polar lines were less likely to need blood transfusions. A trend towards higher Fuhrman grades in patients receiving transfusions suggests a potential link between tumor aggressiveness and bleeding risk.

Conclusions: Our findings provide insight on the utilization of the R.E.N.A.L. nephrometry score in forecasting perioperative, post-surgical, and oncological results. Such data might help optimize surgical methods and pre-operative patient counseling.

Infertility is usually defined as the inability of a couple to conceive even after 1 year of unprotected, frequent sexual intercourse. The male is solely responsible in about 20% of cases. Several risk factors as well as urogenital abnormalities,endocrinological disease,enviromental toxines,genetic disorders,immunological factors,urogenitaly infections,sexual dysfunction  have been identified as causes of male infertility. Nowadays different studies reported mithocoldrial dysfunction as cause of male infertility and alteration of semen parameters.

Introduction and objective: Penis enlargement through substance injection is common in many countries of Southeast Asia and Eastern Europe. The definitive therapy involves removing the entire skin and the subcutaneous tissue and resurfacing the penile shaft via a single-stage or multi-staged procedure. This study aimed to report the functional outcome and esthetics of treating penile paraffinoma patients using the scrotal tunnel + ventral inverted V incision + anastomosis inverted Y technique.

Material and methods: This study was a single-center retrospective descriptive analysis of patients who underwent one-stage scrotal tunnel + ventral inverted V incision and inverted Y-shaped anastomosis procedures from January 2013 to December 2023. The following data were collected: chief complaint, reason for the injection, type of fluid injected, duration of surgery, duration of hospitalization, length of follow-up, and results after surgery.

Results: Of the 32 patients included in the study, 78% injected liquids in the form of oil and the goal of the majority of patients was penis enlargement (71%). The average age was 36.84 years, and the main complaint was pain in the penis during erection (53%). The average operation time was 130 minutes, hospitalization duration was 2.21 days, primary wound healing was 91%, patient satisfaction level was 97%, and Scale 4 erection hardness was 91%.

Conclusion: One-stage surgery for penile paraffinoma produced promising results when the granuloma was limited to the penis and healthy scrotal skin was available to cover the penis.

Background: Erectile dysfunction (ED) and sex hormone profile disturbances are common in ESRD patients.

Objective: To assess the effect of kidney transplant (KT) and Hemodialysis/peritoneal dialysis (HD/PD) on the serum sex hormone profile and sexual functions in ESRD patients with ED.

Patients and methods: A single-center, nonconcurrent cohort study included a hundred ESRD patients with ED, on regular HD/PD (group A, n = 50) and after KT (group B, n = 50) at Armed Forces Hospitals Southern Region, KSA.

Results: the mean age of patients was 47.3 ± 7.01 and 56.8 ± 9.6 years in groups A and B, respectively. The cohorts were comparable regarding patient demographics, apart from a higher incidence of comorbidities in group B. After KT the mean testosterone level was higher in Group B (13.64 ± 3.21 nmol/L vs 10.26 ± 3.26 nmol/L, p < 0.001). Similarly, LH and prolactin levels were lower in group B than in group A (p < 0.05). As regards sexual function, ED was reported in 92% of patients in group A compared to 42% in group B (p < 0.001). In groups A and B, mild ED was found in 48% and 14% of patients, while moderate ED was found in 16% and 8%, respectively. The mean total IIEF-15 score was 36.42 ± 9.33 and 43.87 ± 9.146 in groups A and B, respectively (p = 0.0001). Sexual desire and orgasm were significantly better in Group B.

Conclusions: Our study showed that kidney transplantation could improve erectile function and restore normal sex hormone levels in ESRD male patients with ED, with better outcomes compared to HD/PD.

Background: This study determined pooled estimates of short- and long-term complications of early versus delayed implantation of penile prosthesis in patients with ischemic priapism.

Methods: We searched Pubmed, ProQuest, Scopus, EBSCOHost, and other sources from January 1, 2013, to March 2023. All study designs were included except animal studies, review articles, and consensus documents. Of the 214 articles, four studies were included in the systematic review, and further meta-analysis included three studies (PROSPERO CRD42023411005).

Results: The short-term complication rate was lower with early implantation than with later implantation (β= -2.08; 95% Confidence Interval [CI] = -3.54, -0.6; p = < 0.05). A similar value was also found in the pooled analysis for long-term outcomes, defined as overall satisfaction rate, which is better with early implantation than later (β = 2.18; 95% CI = 1.35, 3.02; p= < 0.05).

Conclusions: The results of the pooled analysis confirmed that short-term complications were significantly lower with early implantation than with delayed implantation. Overall satisfaction rates were higher in early implantation than in delayed implantation of penile prostheses.
