Comparative Study
Comparisons of cancer detection rate and complications between transrectal and transperineal prostate biopsy approaches - a single center preliminary study.
Prostate biopsy remains the gold standard approach to verify prostate cancer diagnosis. Transrectal (TR) biopsy is a regular modality, while transperineal (TP) biopsy is an alternative for the patients who display persistently high levels of prostate-specific antigen (PSA) and thus have to undergo repeat biopsy. This study aimed to compare the cancer detection rates between TR and TP approaches and assess the post-bioptic complications of the two procedures. Besides, the feasibility of performing TP biopsies under local anesthesia was also evaluated. ⋯ Patients receiving TP biopsy are less likely to manifest infection-related complications. Therefore, TP biopsy is a more feasible local anesthetic approach for prostate cancer detection if there are concerns for infectious complications and/or the risk of general anesthesia.

Although the indications of minimally invasive treatments for pediatric urolithiasis are similar to those in adults, it is still crucial to make the right treatment decision due to the special considerations of children. This review aims to evaluate the efficacy and safety of extracorporeal shockwave lithotripsy (SWL), percutaneous nephrolithotomy (PCNL), and retrograde intrarenal surgery (RIRS) in the management of pediatric upper urinary tract stones. ⋯ Although SWL as an outpatient procedure provides shorter hospital stay and reduces operative time, it has a lower SFR and higher retreatment rate than the other two treatments. PCNL exhibits a higher SFR and EQ than SWL; nevertheless, it has a longer operative time and fluoroscopy time than the other two procedures. RIRS offers a similar SFR as PCNL but a lower efficiency than PCNL.
