Over the past 15 years in Australia, the total number of stone treatment procedures has increased significantly. Considerable increases in ureteroscopy were observed with relative and absolute reductions in SWL and PCNL. Regional variations in urolithiasis management strategies highlight the need for consensus on stone treatments within Australia.
Background
Transperineal biopsy (TPB) of the prostate has been increasingly utilized as it has reduced infection risks. Traditionally however, it is performed under general anaesthesia, thus it carries a differing set of risks. Recently, new studies have performed TPB under local anaesthesia with success. In the present study, we explored our experience of performing TPB under local anaesthesia in an Australian cohort.
Methods
In this prospective study based at a metropolitan outpatient clinic, patients were provided with TPB under local anaesthesia. We assessed prostate cancer detection rates, complication rates and patient tolerability. Pain tolerability was assess using patient reported pain score on the visual analogue scale. Follow up data was collected at days 7 and 30 post‐biopsy via telephone interview.
Results
A total of 48 patients were enrolled in this study between June 2020 and March 2021. Median age was 65.5 years and median PSA was 6.95 ng/mL. Clinically significant prostate cancer was detected in 58% of patients. During the procedure, pain scores were rated the highest during infiltration of local anaesthetic agent with a median score of 5. By the conclusion of the procedure, median pain score was 1. Vast majority of patients (85.4%) would opt for a repeat TPB under local anaesthesia should the need for prostate biopsy arise again. Two of our patients experienced infectious complications, and one experienced urinary retention.
Conclusion
Our data is in line with currently available data and confirms that TPB under local anaesthesia can be achieved in a safe and tolerable manner.
Testicular teratoma is a sub-type of Non-Seminomatous Germ Cell Tumour (NSGCT) and often occurs in two distinct age groups. Adult testicular teratomas are often mixed and are malignant. Teratoma can be divided histologically into mature and immature. Pure mature teratoma of the testis is rare. Intratubular Germ Cell Neoplasia (ITGCN) is a common feature associated with teratoma. Teratoma is frequently chemoresistant and clinical management of these tumours includes radical inguinal orchidectomy followed by Retroperitoneal Lymph Node (RPLND) dissection if indicated. Long-term oncological outcomes for mature and immature testicular teratoma are equivocal. Me d ic a l & S urgic a l U ro lo gy
Spermatocytic seminoma (SCS) with sarcoma is an extremely rare testicular tumor with only 11 cases previously described in the literature. We present the 12th case of SCS with sarcoma in a 29-year-old male. SCS itself is an uncommon germ cell tumor with a relatively indolent clinical course that mostly affects males around the fifth decade of life. Sarcomatous differentiation of SCS occurs in 5% to 6% of cases and correlates with a higher possibility of metastatic disease and a poor prognosis. Clinically, this tumor manifests as a slow-growing testicular mass often with an accelerated period of secondary growth. After a concise review of the literature, we conclude that SCS with sarcoma should be treated by radical inguinal orchidectomy with strong consideration given to adjuvant chemotherapy.
Objectives
To compare data on transperineal template biopsy (TPTB) under general anesthesia (GA) compared with local anesthesia (LA) procedures using the PrecisionPoint™ Transperineal Access System (PPTAS) in relation to tolerability, cancer detection rate, complications, and cost.
Methods
A prospective pilot cohort study of patients undergoing transperineal biopsy was performed. Patients were excluded if they had concurrent flexible cystoscopy or language barriers. Patients had a choice of GA or LA. A prospective questionnaire on Days 0, 1, 7, and 30 was applied. The primary outcome was patient tolerability. Secondary outcomes were cancer detection rate, complication rate, and theater utilization.
Results
This study included 80 patients (40 GA TPTB and 40 LA PPTAS). Baseline characteristics including age, prostate‐specific antigen (PSA), digital rectal examination (DRE), findings, and prostate volume were comparable between the groups (p = 0.3790, p = 0.9832, p = 0.444, p = 0.3939, respectively). Higher median prostate imaging‐reporting and data system (PI‐RADS) score of 4 (interquartile range [IQR] 2) versus 3 (IQR 1) was noted in the LA group (p = 0.0326). Pain was higher leaving recovery in the GA group however not significantly (p = 0.0555). Median pain score at LA infiltration was 5/10 (IQR 3), with no difference in pain at Days 1, 7, or 30 (p = 0.2722, 0.6465, and 0.8184, respectively). For GA versus LA, the overall cancer detection rate was 55% versus 55% (p = 1.000) with clinically significant cancer in 22.5% versus 35% (p = 0.217). Acute urinary retention (AUR) occurred in 5% of GA and 2.5% of LA patients (p = 1.000). The GA cohort spent longer in theater and in recovery with a median of 93.5 min versus 57 min for the LA group (p = <0.0001).
Conclusion
This study demonstrates that transperineal biopsy is safely performed under LA with no difference between the cohorts in relation cancer detection or AUR. LA biopsy also consumed less theater and recovery resources. A further larger prospective randomized controlled trial is required to confirm the findings of this study.
