We report the successful 12-month functional recovery of a 46-year-old male who presented with a delayed penile fracture and associated urethral tear managed 72 hours post-trauma. Despite the delayed presentation, the patient achieved excellent outcomes following meticulous surgical repair combined with a three-month postoperative penile rehabilitation protocol using daily Tadalafil.

Management of a penile fracture associated with a urethral injury constitutes an absolute surgical emergency. The primary objective is to prevent fibrotic complications arising from post-traumatic tissue remodeling. Early intervention aims to avert erectile dysfunction (ED) and the development of acquired penile curvature, which can mimic Peyronie’s disease [1].

According to the literature, urethral involvement occurs in approximately 3% to 20% of penile fractures, a factor historically linked in some cohorts to an increased risk of long-term erectile complications. However, contemporary data nuance this perspective; recent studies and specific clinical evaluations demonstrate that a concomitant urethral tear, when managed through precise and prompt anatomical reapproximation, does not necessarily compromise the ultimate functional outcome. Although the healing process begins immediately following the trauma, pathological fibrosis develops progressively [2][3].

During the early phase (approximately 1 to 4 months), prevention relies on the complete evacuation of the hematoma. This is followed by a maturation phase of 3 to 6 months, during which a contractile fibrous plaque may form. Physiologically, this fibrosis leads to a loss of elasticity and decreased compliance of the erectile tissue. This impaired distensibility prevents effective compression of the sub-tunical veins, resulting in venous leak (corporo-veno-occlusive dysfunction). Furthermore, the resulting anatomical curvature may cause a deformity during erection (chordee), making intromission difficult and leading to functional ED [4].

The architecture of the sinusoidal spaces is altered by the invasion of fibrous tissue. The replacement of specialized erectile tissue by dense collagen (Types I and III) reduces the overall rigidity of the penis. Urethral injury leading to urinary extravasation into the peri-urethral and cavernous tissues further exacerbates this condition. Due to its chemical composition, urine induces an acute caustic inflammation that excessively stimulates fibroblasts. This synergy between urinary chemical aggression and the traumatic scarring process establishes the mechanism for erectile dysfunction, combining venous leakage with a deviating mass effect [5].

RationaleofSurgicalTiming:TherapeuticWindowandBiochemicalFactorsofHealing

While surgical intervention performed within the optimal timeframe (within the first 6 to 12 hours following trauma, and no later than 24 hours) remains the gold standard to prevent local inflammatory reactions and anatomical distortion, delayed presentations still benefit from rigorous intervention:

ControloftheInflammatoryPhaseandCytokines: Immediately following rupture, the coagulation cascade releases growth factors (PDGF, TGF-beta, VEGF). Early suture aligns tissue edges before excessive chronic inflammation sets in, whereas delayed management risks overexpressing TGF-beta and promoting fibrosis [6].

CollagenTurnoverandCross-linking: The tunica albuginea relies on orderly type I and III collagen fibers. Precise anatomical reapproximation allows fibroblasts to synthesize a functional extracellular matrix restoring mechanical strength [7].

OxygenMetabolismandMicrocirculation: Rapid hematoma evacuation relieves ischemia and restores oxygen tension, ensuring proper activity of lysyl oxidase—the copper- and vitamin C-dependent key enzyme catalyzing intermolecular collagen cross-links for scar strength.

ChallengesofPenileFractureManagementinSub-SaharanAfrica:AKinshasaPerspective

In Kinshasa, as in many major sub-Saharan African metropolises, the surgical management of penile fracture frequently suffers from therapeutic delay, with interventions often occurring well beyond the optimal 6-to-12-hour window. This delay is driven by specific sociocultural, structural, and economic barriers:

TabooandSecrecy: Feelings of shame, guilt, and the fear of social judgment prompt patients to conceal the injury and attempt ineffective self-treatment at home.

TherapeuticItinerancy: Initial recourse to traditional healers or non-specialized peripheral health structures exacerbates tissue damage and delays proper referral to a urologist.

FinancialBarriers: The lack of universal health coverage and reliance on an out-of-pocket payment system require patients to urgently gather funds, prolonging the pre-surgical interval.

LogisticalConstraints: Chronic traffic congestion in Kinshasa and the saturation of major referral centers hinder rapid access to specialized care.

BridgingtheGap:TheRoleofDelayedRepairCombinedwithPenileRehabilitation

In the present case, despite a delayed presentation of 72 hours post-trauma, complete evacuation of the hematoma combined with meticulous suturing of both the urethra and the tunica albuginea successfully curbed the fibrotic process and limited the progression of ED. This demonstrates that while a delay complicates anatomical restoration, it does not preclude favorable functional recovery when surgical execution is meticulous and complemented by supportive therapeutic strategies [8].

To contextualize the recovery achieved despite the delayed window, it is helpful to examine the proposed cellular and molecular dynamics of corporal tissue protection. Mechanistically, postponed surgical intervention and prolonged micro-environmental hypoxia are hypothesized to upregulate hypoxia-inducible factor 1-alpha (HIF-alpha), which subsequently drives excessive transforming growth factor beta (TGF-beta) signaling and extracellular matrix protein deposition.

Within this framework, the daily administration of Tadalafil 5 mg for three months was introduced as a plausible contributory factor to the patient’s recovery, serving to mitigate fibrotic remodeling. While preclinical and clinical data in other urological contexts (such as post-prostatectomy rehabilitation or Peyronie’s disease) suggest that phosphodiesterase type 5 inhibitors exert anti-fibrotic, anti-apoptotic, and antioxidant effects—and recognizing that specific clinical data regarding PDE5i use explicitly following penile fracture remain scarce—daily low-dose administration is hypothesized to maintain a steady-state plasma concentration, improve tissue oxygenation, and support nocturnal erections [9].

These nocturnal events theoretically provide mechanical stretching to prevent micro-adhesions and maintain sinusoidal perfusion. However, because this report describes a single isolated case, direct cause-and-effect efficacy of the rehabilitation protocol cannot be independently established.

Clinical evaluation via the IIEF-5 score (22/25) and Color Doppler Ultrasound confirms a favorable clinical outcome, though further prospective studies incorporating advanced functional evaluations (such as cavernosography or uroflowmetry) are necessary to substantiate these mechanistic hypotheses and help establish standardized international rehabilitation algorithms for delayed penile trauma cases [10].

Post-traumatic erectile dysfunction in this clinical setting stems from a cascade of intertwined events where trauma-induced fibrosis and urinary extravasation act as powerful catalysts for pathological tissue remodeling. This case highlights that a comprehensive strategy—integrating meticulous delayed surgical repair of both the tunica and the urethra alongside proactive pharmacological prophylaxis with PDE5 inhibitors—is highly effective in limiting scar density, counteracting delayed ischemic damage, and preserving long-term erectile and voiding function.

Written informed consent was obtained from the patient for the publication of this case report and any accompanying clinical images, and the study protocol was conducted in accordance with the ethical standards of the institutional review board of the Cliniques Universitaires de Kinshasa.
