The earliest recorded efforts to biopsy prostate, in the early 20th century, were made through transperineal (TP) approach, with open perineal prostate biopsy (PBx) being considered the gold standard for prostate cancer (PCa) diagnosis in that era. Later, to minimize morbidity and increase diagnostic accuracy, several technical modifications and transrectal ultrasound (TRUS) assistance were incorporated. However, in the 1980s, the transrectal (TR) approach became the predominant PBx method following the introduction of TRUS-TR PBx with sextant sampling, providing a convenient and efficacious method for prostate sampling. With modernization of PCa diagnosis, a recent resurgence of the TP PBx has been observed, driven primarily by TR drawbacks of infectious complications and sampling limitations. TP PBx is rapidly emerging as the new PBx standard, being officially recommended as the initial approach for biopsy in Europe and is increasingly being conducted and studied in the United States. The modern era of TP PBx is based on the improvements in local anesthesia techniques, TP access systems, and robotic assistance. These modifications and advancements have improved the ease of use, patient comfort, and diagnostic outcomes with TP PBx. Herein, we present a history of the evolution of TP PBx spanning over 100 years and explore the basis of the technique that merits future utilization.

Introduction: One of the most challenging aspects of inflatable penile prosthesis (IPP) surgery is reservoir placement. The traditional space of Retzius (SOR) is not suitable for all patients. For example, radical cystectomy or prostatectomy may alter the anatomical SOR. Hence, traditional placement of the reservoir in this space increases the risk of bowel or vascular injury. Also, patients with bilateral inguinal hernias repaired with mesh, or those with previous reservoirs that have been retained, are not eligible for a Retzius reservoir. Our study reports on the use of midline sub-rectus muscle placement of a penile prosthesis reservoir in these patients as an alternative to high submuscular placement commonly used.

Methods: A retrospective chart review of male patients who underwent IPP surgery between June 2017 and 2021 was conducted. Patients were divided into two groups based on the location of the reservoir: SOR versus Midline Submuscular Reservoir (MSMR). Complication rates were compared, including herniated reservoirs, infections, bowel injuries, and vascular injuries.

Results: Our cohort included 461 patients who underwent IPP surgery between June 2017 and 2021 in one tertiary center. SOR was used in 89% of patients and MSMR in 11% of patients (n = 413 and 48, respectively). Median follow-up for all patients was 28 months. The mean age was 67 ± 8 years. There was no statistically significant difference between the two groups regarding age or comorbidities (BMI, diabetes mellitus, hypertension, hyperlipidemia, and coronary artery disease). The complication rate was low in both the SOR and MSMR groups, with device malfunction being the most common (2% versus 4%, respectively; p = 0.32). The infection rate was 0.5% in the SOR group with no infections in the MSMR group (NS). There was only one case of herniation requiring surgical revision in the SOR group and no cases of bowel or vascular injury.

Conclusion: Placement of a penile prosthesis reservoir within a midline rectus submuscular space is a safe and effective technique when the SOR is compromised by previous surgery or bilateral inguinal canals are not accessible.

Background: Although paediatric ureteroscopy is widely performed, there is still a lack of data and outcomes in early childhood. In this two-centre study, we compared the outcomes of ureteroscopy for stone disease management in early and late childhood and provide outcomes for the same.

Methods: Data was retrospectively collected on consecutive patients from two tertiary paediatric endo-urology European centres over a 15-year period (2006-2021). Patients were split into two groups, namely, early childhood (age ⩽ 9 years) and late childhood (age 9 to ⩽16 years). Outcomes including stone-free rate (SFR) and complications were compared between these two groups.

Results: A total of 148 patients underwent 184 procedures (1.2 procedure/patient) during the study period (66 in early childhood and 82 in late childhood). The mean age in early and late childhood groups were 5.6 and 13.3 years, and a male: female ratio of 1.6:1 and 1.1:1, respectively. The SFR and complications in early and late childhood groups were 87.8% and 90.2% (p = 0.64) and 5.7% and 4.1%, respectively.

Conclusion: Paediatric ureteroscopy and laser stone fragmentation achieves good results in both early and late childhood with comparable SFRs, although the complications and need for second procedure were marginally higher in the early childhood group. Our study would set up a new benchmark for patient counselling in future, and perhaps this needs to be reflected in the paediatric urolithiasis guidelines.
