Penile urinary sheaths: a continence management system for men.

Urinary leakage is prevalent in men. To contain and manage this leakage, men are often advised about urinary devices. However, sometimes this advice does not include penile sheaths. Penile sheaths are a good way of managing urinary leakage if an individual is suitable for sheaths. This article will explore this suitability, advantages to using a sheath, reasons why sheaths may not be suitable, and will discuss optimum fitting to ensure the sheath is a secure drainage device.

Successful Endovascular Microembolization for Post-Traumatic High-Flow Priapism: A Case Report.

BACKGROUND High-flow (non-ischemic) priapism is a rare urological condition usually related to blind trauma to the penis or perineum causing an arterial-lacunar fistula. It can be treated conservatively, but in some cases when conservative treatment fails, the interventional approach is indicated. In the past, only surgical treatment was available, which was associated with a significant risk of complications. Endovascular techniques use a novel approach and offer clinical benefits for the patient. CASE REPORT A 51-year-old man was admitted to the hospital after referral from the urology department with high-flow priapism related to blunt trauma. Angio-computed tomography showed extravasation of contrast medium to the corpus cavernosum, and angiography revealed a fistula between the distal segment of the left internal pudendal artery and corpora cavernosa. A successful endovascular microembolization of the arterial-lacunar fistula with the use of microcoils was performed. The postprocedural period was uneventful and the patient was discharged. Despite incomplete angiographic follow-up at 6 months, the initial symptoms were fully resolved with the absence of any erectile dysfunction and no recurrence of priapism occurred. CONCLUSIONS Post-traumatic high-flow priapism can be safely and effectively treated by endovascular means. Microembolization has proven to be successful and beneficial to preserve sexual functions.

Effects of ketamine on penile tissues in an experimental priapism model in rats.

BACKGROUND: This study aimed to evaluate the histopathological and biochemical effects of ketamine on penile tissues following ischemia-reperfusion injury induced by priapism. METHODS: Twenty-four male rats were randomized into three groups. Group 1 served as the control group. Group 2 underwent the priapism model to induce ischemia-reperfusion injury. Group 3, the treatment group, experienced a similar ischemia-reperfusion model as Group 2; additionally, 50 mg/kg of ketamine was administered intraperitoneally just before reperfusion. Blood biochemical analyses and penile histopathological evaluations were performed. RESULTS: In Group 3, significant improvements were observed in all histopathological scores, including desquamation, edema, inflammation, and vasocongestion compared to Group 2 (p<0.001). Blood biochemical analyses showed that the malondialdehyde (MDA) levels were recorded as 10 in Group 2, with a significant decrease in Group 3 (p=0.013). Similarly, proinflammatory cytokine levels, including interleukin-1 beta (IL-1ß), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α), were found to be suppressed in Group 3 compared to Group 2 (p=0.003, p=0.022, and p=0.028, respectively). Antioxidant enzyme activities, such as glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD), were higher in Group 3 compared to Group 2 (p=0.016 and p=0.024, respec-tively). CONCLUSION: Ketamine is an effective anesthetic agent in alleviating the effects of penile ischemia-reperfusion injury.

[Clinical case of penile fracture].

A clinical case of a penile fracture as a result of an unsuccessful sexual intercourse, which later required surgical treatment in the form of corporoplasty with opening and draining of the hematoma, is discussed in the article. Penile fracture is a rare urological emergency that requires immediate medical attention to avoid long-term complications, including penile curvature and erectile dysfunction.

Widening of narrow urethral plates with lateral skin in TIP hypospadias repair: single center series.

BACKGROUND: To compare the outcomes of hypospadias repair using tubularized incised plate (TIP) urethroplasty and modified TIP with lateral skin to widen the urethral plate (WTIP). MATERIALS AND METHODS: Data were obtained from pre-pubertal boys who underwent primary hypospadias repair between May 2018 and July 2023. The cases were divided into two groups; one group underwent TIP with urethral plate ≥ 6 mm width and the other group with urethral plate width < 6 mm underwent WTIP. WTIP urethroplasty was performed by widening incisions on the outer margins of the urethral plate to incorporate penile and glandular skin lateral to the urethral plate to facilitate tubularization. Complication rates and urinary functions were compared. RESULTS: A total of 157 patients were enrolled in this study. Eighty-eight cases with narrow urethral plate were subjected to WTIP urethroplasty, and the rest were subjected to TIP urethroplasty. The preoperative glans width in WTIP group was less than that in TIP group (P < 0.001), and 44.3% had midshaft meatus in WTIP group compared to 17.4% in TIP group (P < 0.001). However, the incidences of postoperative complications (17.6% vs. 21.6%, P = 0.550) were not statistically different between the TIP and WTIP groups. In addition, both groups did not differ significantly in postoperative uroflowmetry assessment. CONCLUSIONS: The described technique helps to create an adequately caliber aesthetic neomeatus and facilitates tubularization, especially in hypospadias with a narrow urethral plate. Our data suggest that augmentation of a narrow urethral plate with WTIP has a similar surgical outcome to that of the TIP procedure in patients with a wide urethral plate.

"Bone in the penis" or fasciitis ossificans of the penis - a first time description of a pseudo-tumor at an extraordinary site.

BACKGROUND: Fasciitis ossificans is a rare subtype of nodular fasciitis, a benign soft tissue tumor with reactive characteristics. Due to its rapid growth, it is often misdiagnosed as a malignant tumor. While fasciitis ossificans commonly originates from the subcutaneous tissue and can appear throughout the body, it may also arise from extraordinary sites. CASE PRESENTATION: We report the first-ever documented case of fasciitis ossificans arising from the penis in a male patient who presented with a tumor on the glans penis. The tumor was surgically resected due to suspicion of penile cancer. Initial histopathological analysis led to a misdiagnosis of squamous cell carcinoma. However, pathological consultation ultimately confirmed the diagnosis of fasciitis ossificans of the penis originating from the glans penis by demonstrating ossification. CONCLUSION: This case underscores the importance of considering fasciitis ossificans in the differential diagnosis of soft tissue tumors, even in unusual locations such as penile soft tissue.

Microscopic Electric Rotary Grinding of Plaques Combined with Graft Repair in the Management of Peyronie's Disease.

Peyronie's Disease (PD) is clinically characterized by the development of localized fibrous plaques, primarily on the tunica albuginea, especially on the dorsal area of the penis. These plaques are the hallmark feature of this condition, resulting in penile curvature, deformity, and painful erections for affected individuals. Although various nonsurgical treatment options exist, their overall effectiveness is limited. As a result, surgical intervention has become the ultimate choice for patients with severe penile curvature deformities and associated erectile dysfunction. Our research team has successfully employed a combined approach involving microscopic electric rotary grinding of the fibrous plaques and the use of tunica vaginalis or bovine pericardium as graft materials for the repairing of the defects of tunica albuginea in the treatment of PD. This approach has consistently yielded highly satisfactory results regarding the restoration of penile shape, with excellent cosmetic results and significantly improved sexual satisfaction. This protocol aims to present a comprehensive surgical management strategy utilizing electric rotary grinding of the plaques and repairing the defects of tunica albuginea by using the tunica vaginalis, which represents an optimal surgical strategy for treating PD.

Renal Cell Carcinoma Metastasis to the Penis: A Case Report and Literature Review.

Metastasis to the penis from renal cell carcinoma (RCC) or any other primary cancer site is unusual; when it does occur, it often involves multiple organs. A 75-year-old man presented with penile pain and swelling. Three months earlier, he had open radical nephrectomy with thrombectomy and was diagnosed with clear-cell RCC with tumor thrombosis in the inferior vena cava. The follow-up imaging indicated metastasis to the penis, prompting a total penectomy due to worsening pain. The excised mass displayed features consistent with metastatic RCC. This case underscores the need to consider rare metastatic sites, such as the metastasis of RCC to the penis, in RCC patients.

MicroRNA-503-5p protects streptozotocin-induced erectile dysfunction in diabetic rats by downregulating SYDE2.

Plentiful studies have clarified miRNAs take on a key role in the sexual dysfunction of diabetic rats. This study aimed to figure out microRNA (miR)-503-5p/SYDE2 axis' latent mechanisms in streptozotocin-induced diabetic rat sexual dysfunction. A model of erectile dysfunction (ED) in diabetic rats was established by injecting streptozotocin. MiR-503-5p and SYDE2 in ED rats were altered by injection of miR-503-5p mimic or si/oe-SYDE2. The targeting link between miR-503-5p and SYDE2 was testified. ICP/MAP value was tested by pressure sensor; Penile capillary abundance was assessed; Penile cGMP and AGEs were detected; penile smooth muscle cell apoptosis was assessed; MiR-503-5p and SYDE2 were tested. In streptozotocin-induced ED rats, miR-503-5p was reduced and SYDE2 was elevated. Elevating miR-503-5p or silencing of SYDE2 can enhance penile erection rate, ICP/MAP value, capillary abundance, and cGMP but reduce AGEs and penile smooth muscle cell apoptosis rate in ED rats. Strengthening SYDE2 with elevating miR-503-5p turned around the accelerating effect of elevated miR-503-5p on penile erection in ED rats. SYDE2 was a downstream target gene of miR-503-5p. MiR-503-5p protects streptozotocin-induced sexual dysfunction in diabetic rats by targeting SYDE2.

A novel strategy to induce penile erection during penile doppler ultrasound: oral sildenafil administration plus alprostadil injection.

OBJECTIVES: To evaluate the efficacy of a novel approach to achieve the optimal penile erection during the penile doppler ultrasound (PDU) examination, which was oral sildenafil combined alprostadil injection. MATERIALS AND METHODS: A total of 60 ED patients were enrolled in our prospective study, and they were randomly assigned to two group with different PDU order. The approaches assisted the PDU included two models, mode A meaning injection of 15 µg alprostadil and model B meaning oral sildenafil 100 mg plus injection of 15 µg alprostadil. The PDU parameters were measured continuously before induced erection, and 5, 10, 15, 20, 25 min. RESULTS: Each group included 30 ED patients with similar clinical characteristics. After pooling the results together, the PSV, EDV, and RI were all improved significantly, when adding the oral sildenafil administration to assist PDU. Also, the clinical response of oral sildenafil administration plus alprostadil injection was better than that in alprostadil injection alone (p = 0.016). The arterial ED were decreased from 31.67% to 15.00% with the P value 0.031, and the mixed ED was also decreased statistically (23.33% vs 8.33%, p = 0.024). CONCLUSION: Oral sildenafil administration plus alprostadil injection could improve the diagnostic accuracy of PDU.

Comparison of the effects of ring block and dorsal penile nerve block on parental satisfaction for circumcision operation in children: randomized controlled trial.

PURPOSE: In children, circumcision is a procedure associated with perioperative pain and parental satisfaction is an important parameter in the evaluation of anesthesia procedures. Inadequate dorsal penile nerve block (DPNB) for the ventral shaft of the penis might impact parental satisfaction negatively. To evaluate this hypothesis, we compared the effects of penile ring block (RB) and dorsal penile nerve block (DPNB) on parental satisfaction. Postoperative pain, need for additional analgesia, intraoperative hemodynamic data, recovery status, side effects, and postoperative complications were evaluated as secondary outcomes between the blocks. METHODS: Parental satisfaction and anesthetic effectiveness of RB and DPNB for circumcision in children were compared. 86 patients were randomized 1:1 to Group RB and Group DPNB, which were administered the same dose of anesthesia. Parental satisfaction was evaluated with the Pediatric Anesthesia Parental Satisfaction Questionnaire (PAPS). Postoperative pain evaluations were made with the Face, Legs, Activity, Crying, Consolability Pain Scale (FLACC). RESULTS: In terms of parent satisfaction, no differences were detected between the groups in the pre-anesthesia, pre-anesthesia and post-anesthesia, post-anesthesia, hospital team, and anesthesia team parameters (p > 0.05). The scores of Group DPNB patients were higher only in the "Q11" subparameter in the "anesthesia team" parameter, and this difference was significant (0.024). CONCLUSION: RB and DPNB were compared in circumcision, which is the most common surgical procedure for children. Parental satisfaction, anesthesia, and analgesic effects of both blocks were found to be similar. CLINICAL TRIALS: ACTRN12622001211752.

Surgical management of complex curvature in Peyronie's disease.

PURPOSE: About 10% of Peyronie's patients are complex cases with severe curvature (>60 degrees), ventral plaque, multiplanar curvature, hour-glass/hinge deformity, notching deformity, and ossified plaque. In patients with complex Peyronie's disease (PD), different techniques (shortening procedures, lengthening procedures, and penile prosthesis implantation (IPP)) may be necessary to achieve successful result. This review aims to analyze the various surgical techniques employed in the management of Peyronie's disease, with a specific focus on patients with complex deformity. METHODS: Articles focusing on the surgical management of complex curvature in Peyronie's disease were searched in MEDLINE and PubMed published between 1990 and 2023. RESULTS: Shortening procedures are linked to penile shortening and are not recommended for complex cases such as notching, hour-glass deformity, or ossified plaque. Lengthening procedures are suitable for addressing complex curvatures without erectile dysfunction (ED) and are a more appropriate method for multiplanar curvatures. Penile prosthesis implantation (IPP), with or without additional procedures, is the gold standard for patients with ED and Peyronie's disease. IPP should also be the preferred option for cases of penile instability (hinge deformity) and has shown high satisfaction rates in all complex cases. CONCLUSION: While surgical interventions for complex curvature in Peyronie's disease carry inherent risks, careful patient selection, meticulous surgical techniques, and post-operative care can help minimize complications and maximize positive outcome.

Penile Enhancement Using Biodegradable Scaffolds Covered with Platelet-rich Plasma-Fibrin Glue, Mesenchymal Stem Cells for Micropenis.

PURPOSE: Evaluation of preliminary cosmetic and functional outcomes of biodegradable scaffolds covered with platelet-rich plasma in penile girth augmentation. MATERIALS AND METHODS: Between June 2016 and June 2018, 36 males who had a mean age of 28.91 years (range 20 - 48 years) with micropenis underwent this procedure. A mixture of platelets-fibrin glue and mesenchymal cells obtained from dermal fat tissue were prepared. Then the mixture was seeded on the pretreated tube-shaped poly lactic-co-glycolic acid scaffold and underwent a whole day of incubation. Following penile degloving, scaffolds were surgically implanted within the interface region of dartos and Buck's fascia. The 5-point Likert scoring scale was used to evaluate the patients' satisfaction with surgery. RESULTS: Patients followed up for 6-12 (8 ± 2.86) months. The penile length in an erected state before surgery was 6.5 - 12.5 cm (9.08 ± 1.6) which enhanced to 7 - 14 cm (10.59 ± 1.71) after surgery (P < .0001). The penile girth before and after surgery were 8.49 ± 1.53 and 10.91 ± 1.96 cm, respectively (P < .0001). An augment in penile length and girth of 1.5 and 2.6 cm were achieved, respectively. Patients appraised surgical intervention on a rating of one to five. The highest possible score (5) was assigned by 27 %, 33 % expressed a very good mark (4), and 19 % gave a good mark (3). CONCLUSION: Covering the scaffold with a mixture of Platelets-Fibrin glue and mesenchymal cells seems a safe and feasible method for penile reconstruction surgery. More studies should be done to determine the effect of platelets- fibrin glue and mesenchymal cells for treating micropenis.

SHH regulates penile morphology and smooth muscle through a mechanism involving BMP4 and GREM1.

BACKGROUND: The cavernous nerve (CN) is frequently damaged in prostatectomy and diabetic patients with erectile dysfunction (ED), initiating changes in penile morphology including an acute and intense phase of apoptosis in penile smooth muscle and increased collagen, which alter penile architecture and make corpora cavernosa smooth muscle less able to relax in response to neurotransmitters, resulting in ED. AIM: Sonic hedgehog (SHH) is a critical regulator of penile smooth muscle, and SHH treatment suppresses penile remodeling after CN injury through an unknown mechanism; we examine if part of the mechanism of how SHH preserves smooth muscle after CN injury involves bone morphogenetic protein 4 (BMP4) and gremlin1 (GREM1). METHODS: Primary cultures of smooth muscle cells were established from prostatectomy, diabetic, hypertension and Peyronie's (control) (N = 18) patients. Cultures were characterized by ACTA2, CD31, P4HB, and nNOS immunohistochemical analysis. Patient smooth muscle cell growth was quantified in response to BMP4 and GREM1 treatment. Adult Sprague Dawley rats underwent 1 of 3 surgeries: (1) uninjured or CN-injured rats were treated with BMP4, GREM1, or mouse serum albumin (control) proteins via Affi-Gel beads (N = 16) or peptide amphiphile (PA) (N = 26) for 3 and 14 days, and trichrome stain was performed; (2) rats underwent sham (N = 3), CN injury (N = 9), or CN injury and SHH PA treatment for 1, 2, and 4 days (N = 9). OUTCOMES: Western analysis for BMP4 and GREM1 was performed; (3) rats were treated with 5E1 SHH inhibitor (N = 6) or IgG (control; N = 6) for 2 and 4 days, and BMP4 and GREM1 localization was examined. Statistics were performed by analysis of variance with Scheffé's post hoc test. RESULTS: BMP4 increased patient smooth muscle cell growth, and GREM1 decreased growth. In rats, BMP4 treatment via Affi-Gel beads and PA increased smooth muscle at 3 and 14 days of treatment. GREM1 treatment caused increased collagen and smooth muscle at 3 days, which switched to primarily collagen at 14 days. CN injury increased BMP4 and GREM1, while SHH PA altered Western band size, suggesting alternative cleavage and range of BMP4 and GREM1 signaling. SHH inhibition in rats increased BMP4 and GREM1 in fibroblasts. CLINICAL IMPLICATIONS: Understanding how SHH PA preserves and regenerates penile morphology after CN injury will aid development of ED therapies. STRENGTHS AND LIMITATIONS: SHH treatment alters BMP4 and GREM1 localization and range of signaling, which can affect penile morphology. CONCLUSION: Part of the mechanism of how SHH regulates corpora cavernosa smooth muscle involves BMP4 and GREM1.

BMP4 and GREM1 are targets of SHH signaling and downstream regulators of collagen in the penis.

BACKGROUND: Cavernous nerve (CN) injury, caused by prostatectomy and diabetes, initiates a remodeling process (smooth muscle apoptosis and increased collagen) in the corpora cavernosa of the penis of patients and animal models that is an underlying cause of erectile dysfunction (ED), and the Sonic hedgehog (SHH) pathway plays an essential role in the response of the penis to denervation, as collagen increases with SHH inhibition and decreases with SHH treatment. AIM: We examined if part of the mechanism of how SHH prevents penile remodeling and increased collagen with CN injury involves bone morphogenetic protein 4 (BMP4) and gremlin1 (GREM1) and examined the relationship between SHH, BMP4, GREM1, and collagen in penis of ED patients and rat models of CN injury, SHH inhibition, and SHH, BMP4, and GREM1 treatment. METHODS: Corpora cavernosa of Peyronie's disease (control), prostatectomy, and diabetic ED patients were obtained (N = 30). Adult Sprague Dawley rats (n = 90) underwent (1) CN crush (1-7 days) or sham surgery; (2) CN injury and BMP4, GREM1, or mouse serum albumin (control) treatment via Affi-Gel beads or peptide amphiphile (PA) for 14 days; (3) 5E1 SHH inhibitor, IgG, or phosphate-buffered saline (control) treatment for 2 to 4 days; or (4) CN crush with mouse serum albumin or SHH for 9 days. OUTCOMES: Immunohistochemical and Western analysis for BMP4 and GREM1, and collagen analysis by hydroxyproline and trichrome stain were performed. RESULTS: BMP4 and GREM1 proteins were identified in corpora cavernosa smooth muscle of prostatectomy, diabetic, and Peyronie's patients, and in rat smooth muscle, sympathetic nerve fibers, perineurium, blood vessels, and urethra. Collagen decreased 25.4% in rats with CN injury and BMP4 treatment (P = .02) and increased 61.3% with CN injury and GREM1 treatment (P = .005). Trichrome stain showed increased collagen in rats treated with GREM1. Western analysis identified increased BMP4 and GREM1 in corpora cavernosa of prostatectomy and diabetic patients, and after CN injury (1-2 days) in our rat model. Localization of BMP4 and GREM1 changed with SHH inhibition. SHH treatment increased the monomer form of BMP4 and GREM1, altering their range of signaling. CLINICAL IMPLICATIONS: A better understanding of penile remodeling and how fibrosis occurs with loss of innervation is essential for development of novel ED therapies. STRENGTHS AND LIMITATIONS: The relationship between SHH, BMP4, GREM1, and collagen is complex in the penis. CONCLUSION: BMP4 and GREM1 are downstream targets of SHH that impact collagen and may be useful in collaboration with SHH to prevent penile remodeling and ED.
