Surgical management and post-operative functional outcomes of patients with a penile fracture-a single centre experience over 10 years.

BACKGROUND: Penile fractures are uncommon urological emergencies which occur when there has been a breach in the tunica albuginea of the corpora cavernosum that may be unilateral and bilateral and can extend to involve the urethra. AIM: To assess the management and outcomes of penile fractures in a single institution in Ireland. METHODS: A retrospective review of the emergency theatre logbooks was performed between 2011 and 2021 to identify patients who had undergone an exploration for a suspected penile fracture. OUTCOMES: Seventeen patients were initially identified on review of theatre logbooks as having an exploration for a suspected penile fracture. Two patients were excluded from the study due to a lack of clinical notes being available. A further 4 patients on chart review were found to not have a penile fracture at exploration. RESULTS: Eleven patients had a confirmed penile fracture intra-operatively, four of whom had an associated urethral injury. Nine (9/11) patients had preserved normal erections post-operatively documented on follow-up; two, however, reported erectile dysfunction requiring phosphodiesterase inhibitors. CLINICAL IMPLICATIONS: Our study supports urgent surgical exploration for penile fractures to ensure good functional outcomes. STRENGTHS AND LIMITATIONS: This is a retrospective review of theatre logbooks to identify patients with a suspected penile fracture. CONCLUSION: The results of our cohort show a good outcome of erectile function following surgical repair of a penile fracture (9/11; 82%). Four patients (4/11; 36%) had a urethral injury diagnosed intra-operatively, one of whom required a formal urethroplasty.

Predictors of Stone-Related Events in Asymptomatic Untreated Intrarenal Calculi.

Purpose: There is a lack of data on the natural history of asymptomatic intrarenal calculi. In this study, we investigate stone-related events (SREs) in patients with untreated intrarenal calculi. We also investigate predictive factors for SREs. Methods: All patients found with an asymptomatic intrarenal calculus on CT kidney, ureter, bladder managed conservatively with interval imaging for ≥6 months were included. Patients were evaluated for any SRE. The rate of event according to calculus size, location, and number of calculi was also analyzed. Multivariate logistic regression analysis was performed to determine significant predictors for SREs. Results: In total, 266 renal units from 177 patients met inclusion criteria. The mean stone size was 4.44 mm (range 1-25 mm). Duration of follow-up was 43.78 ± 26.86 months (range 6-106 months). The overall rate of SREs, including intervention (n = 80) and spontaneous stone passage after ureteral colic (n = 40), was 45.1% (n = 120/266). Stones >5 mm were more likely to lead to an event compared with stones ≤5 mm (odds ratio [OR]: 2.94; p = 0.01). Interpolar stones and stones located in multiple calices were more likely to cause a SRE than lower pole stones (OR: 2.05; p = 0.05 and OR: 2.29; p = 0.03, respectively). Conclusion: In this large series of patients with asymptomatic intrarenal calculi, the incidence of a spontaneous SRE was 45.1% after 41 months. Stone size and stone location were significant predictors for a SRE. Information from this study will enable urologists to accurately risk stratify patients with asymptomatic renal stones.
