Clinical spectrum, diagnosis, and sexual dysfunction after repair of fracture penis: Is no news good news?

Imaging findings in suspected penile fracture: alternative diagnoses and surgical correlation

OBJECTIVES

The primary objective is to compare the imaging and surgical findings in a cohort of patients with suspected penile fracture (PF).

METHODS

Retrospective cohort study of all patients with suspected PF over an 11-year period at a tertiary referral andrology centre. All dedicated presurgical imaging with ultrasound (US) and MRI was analysed and correlated with intraoperative findings; alternative diagnoses were recorded.

RESULTS

One hundred and ninety-three patients were included. One hundred and four (54%) had alternative diagnoses to PF including dorsal vein rupture and haematoma. Ninety-nine (51%) underwent surgical exploration of which 89 (46%) had PF. US correctly confirmed the presence and marked the site of fracture in 92% of cases. MRI was primarily used as a problem-solving tool (13 cases) and demonstrated a more extensive injury than US (12 cases). The reported size of tunical defect on imaging was a median of 7 mm (IQR 4-10) significantly smaller than on exploration (median 20 mm, IQR 10-30; P < .0001).

CONCLUSIONS

US has a high positive predictive value in the confirmation of PF. MRI improves the detection and characterizing the extent of injury. Imaging marking informs surgical incision but defect size is under appreciated on all imaging modalities.

ADVANCES IN KNOWLEDGE

Penile imaging has a high positive predictive value to not only confirm the diagnosis of PF but to stage the extent of injury and mark the skin, which impacts the surgical technique. Alternative diagnoses to fracture are common and imaging could prevent unnecessary surgical exploration.

An unusual presentation of penile fracture with complete transection of urethra: a case report

Penile fracture is one such urologic emergency that occurs when the penis is struck bluntly during sexual activity, and in less than 5-10% of cases, the concurrent urethral damage is evident, but complete transection is very rare. A 37-year-old male presented with a history of 'snap' sound and immediate detumescence of penis during intercourse, when he fell and hit the pubic bone of his partner. There was acute retention of urine, an attempt to pass a catheter failed and the patient underwent supra-pubic catheterization. On examination, there was classical 'eggplant deformity' of the penis with blood at the tip of the meatus. MRI showed a tunical tear on both sides at the penoscrotal junction with indistinct urethra and extensive hematoma in the proximal penile shaft. Surgical management was successfully done by anastomotic urethroplasty and cavernosal repair.

Penile Trauma Burden and Aetiology in the Paediatric and Adult Population: A Scoping Review and Critical Analysis of the Literature

Penile trauma is rare. It is associated with the impairment of physiological functions and deterioration in patients' quality of life. Currently, the relevance of age demographics in the occurrence of this debilitating injury has not been well discussed. The objective of this study was to provide a scoping review of penile trauma within the lens of the legal age of maturity. A search of the PubMed, Scopus and Web of Science databases was conducted, and then, the identified publications were used to conduct this scoping review focussing on the study aim. The results identified were categorised into five themes. This included publication information (author, year, country, study duration); demographic information (age of presentation, number of patients, relative burden); penile trauma clinical pattern (type, severity, associated injury), risk factors and clinical consequences. While mobile and active young adults were at risk of outdoor trauma, the report on penile trauma in the paediatric population is rare and usually focussed on sexual trauma. Penetrating trauma has been more extensively studied in comparison to blunt penile trauma despite the significance of the latter in the paediatric population. Injury severity classification is not available for most studies limiting their usefulness in the universal comparison of trauma severity and injury prognostication. There is a diversity in the burden and presentation of penile trauma. Available research studies are limited in the paediatric population, mostly focussed on penile fracture in adults and generally devoid of a standardised penile trauma severity description. Additional studies with a specific focus on penile trauma are required to characterise aetiological risks and injury severity across the legal age of maturity.

Comparison of closure versus non-closure of the intraoral buccal mucosa graft site in urethroplasties. A systematic review and meta-analysis

Aim

To assess postoperative oral morbidity through meta-analysis of comparative studies for closure or non-closure of the buccal mucosa graft harvest area in patients undergoing urethroplasty.

Methods

A systematic literature review was conducted in January 2022. Randomized controlled studies were assessed according to the Cochrane collaboration guidelines. Postoperative pain, difficult mouth opening, alteration of oral salivation, perioral numbness, and tolerance of solid and liquid intake results were assessed. Standard mean differences and risk ratios with 95% confidence intervals were estimated for relative risk. Assessment was performed with subgroup analyses according to time points.

Results

This meta-analysis included 373 patients in 7 randomized studies. The oral pain overall pooled effect estimates were investigated for the time points of day 0-1, day 3-7 and months 1-6. According to corrected effect estimates after sensitivity analysis, at the day 0-1 time point, the non-closure group was significantly superior compared to the closure group. But there was no difference at the other time points and in total. The overall pooled effect estimates for difficult mouth opening were investigated at 4 time points (day 1, days 5-7, months 1-3 and months 6). After sensitivity analysis, the overall pooled effect estimates at 6 months were significantly superior for the non-closure group. There were no significant differences between the non-closed and closed groups based on the overall pooled-effect estimates for oral numbness, salivary secretion alteration, and tolerance of liquid and solid food variants.

Conclusion

The non-closure group was more advantageous in terms of oral pain in the early postoperative period. There were no differences between the groups in terms of alteration of salivation, oral numbness and toleration of liquid/solid food. Although the non-closed group seems more advantageous in terms of ease in mouth movements, more studies are needed to prove this.

Penile fracture with urethral rupture: The feasibility of repair through penoscrotal approach

Penile fracture with an associated urethral injury is a rare urological emergency resulting from trauma to the erect penis during vigorous sexual intercourse. The patient often presents with swelling of the penis, discoloration of the penile skin, localized pain, and hematuria with a typical history of sudden detumescence during intercourse. Subcoronal penile degloving incision has been conventionally described and is frequently used by many clinicians for the management of penile fracture-urethral injury. Here, we describe a case of complex penile fracture managed through the vertical penoscrotal incision. The penoscrotal approach confers excellent exposure to both the ruptured corpus cavernosum and urethra. This approach ensures successful outcomes in such an emergency procedure without having disadvantages of the degloving incision.
