Testosterone (T) therapy (TTh) in men with T deficiency who have undergone radical prostatectomy (RP) for prostate cancer remains controversial. We aimed to assess the impact of TTh on biochemical recurrence (BCR) rates after RP in men with low-intermediate organ-confined disease. This study included men who underwent an RP at our institution for organ-confined prostate cancer and had grade groups 1 to 3 on RP pathology. A Cox model was created for time to BCR with T use included as a time-dependent covariate, adjusted for age, preoperative PSA, grade group at RP, and the presence of comorbidities. A landmark analysis was used: Patients were included in the analysis if their last PSA in the 18 weeks postoperatively was undetectable and they had not had BCR or been lost to follow-up by that point, and follow-up for BCR began at 18 weeks. BCR was defined as a PSA ≥ 0.1 ng/mL after RP with a second confirmatory rise ≥ 0.1 ng/mL. The study population included 5199 men after RP, with 198 patients receiving T at any point after RP and 5001 not receiving T. The median age was 59 (interquartile range, 55-65) and 61 (interquartile range, 56-66) years, respectively. Men in the T group tended to present with more vascular comorbidities. For those receiving T, clomiphene citrate was prescribed in 49% of men, 32% received transdermal T, and 19% intramuscular T. We found a nonsignificantly decreased risk of BCR associated with the use of T after RP (hazard ratio, 0.84; 95% CI, 0.48-1.46; P = .5), and overall rates of BCR were low, with probability of BCR at 5 years less than 2% in both groups. TTh can be given to select men after RP. We found no evidence that administration of TTh after RP causes BCR.

Objective: To define the impact of varicoceles (VX) on total testosterone (TT) levels in an aging male population. Methods: This retrospective analysis of a departmental database assessed patients ≥50 years of age, who had 2 testes, and recorded early morning TT levels. Patient demographics, comorbidity profiles, VX laterality, and VX grade were also analyzed. Results: Data were retrievable for 776 patients. Mean age was 66±12years. Around 140 (18%) patients had at least 1 VX on examination (VX+). Of these 118 (84%) had unilateral VX while 22 (16%) had bilateral. Mean TT for the VX+ group (336ng/dL±168) was statistically significantly lower than for the VX- group (472ng/dL ±267) (P<.01). Those with bilateral VX had lower TT (297ng/dL) than those with unilateral VX (372ng/dL) (P<.05). While 16% of the total VX+ population had TT levels <300ng/dl, these rates were 11% and 24% in men with unilateral and bilateral VX (P<.01). In those with unilateral VX, there was a relationship between VX grade and testosterone deficiency, with the highest likelihood associated with Grade III (r=0.65, P<.01). There was no association between Grade I and low T levels. Conclusions: In this population of men older than 50, the presence, laterality, and grade of VX were associated with lower levels of TT.

Objective: Multiparametric MRI and the transperineal approach have become standard in the diagnostic pathway for suspected prostate cancer. Targeting of MRI lesions is performed at most centers, but the routine use of systematic cores is controversial. We aim to assess the value of obtaining systematic cores in patients undergoing cognitive fusion targeted double-freehand transperineal prostate biopsy. Methods: Patients who underwent a cognitive fusion, freehand TPB at a single tertiary urology service (Perth, Australia) between November 2020 and November 2021 were retrospectively reviewed. Patients were included if they were biopsy naive and had a clinical suspicion of prostate cancer, based on their mpMRI results. Both targeted and systematic cores were taken at the time of their biopsy. Results: One hundred forty patients suited the selection criteria. Clinically significant cancer was identified in 63% of patients. Of those that had clinically significant cancer, the target lesion identified 91% of the disease, missing 9% of patients whom the target biopsy detected non-clinically significant cancer but was identified in the systematic cores. Higher PI-RADS category patients were also found to be associated with an increasing likelihood of identifying clinically significant cancer within the target. Conclusions: In patients with PI-RADS 3 and higher, the target biopsy can miss up to 9% of clinically significant cancer. Systematic cores can add value as they can also change management by identifying a high-risk disease where only intermediate cancer was identified in the target. A combination of targeted and systematic cores is still required to detect cancer.

Here we present two cases of post-operative obstructive renal failure following major abdomino-pelvic sarcoma surgery. In both cases, prophylactic ureteric stents were inserted to aid the identification and protection of the ureters during resection of these complex retroperitoneal masses. In case one, obstructive renal failure occurred following ureteric stent removal on day 0 post-operatively. In case two, obstructive renal failure developed on day 1 post-operatively despite having a ureteric stent in situ. Here we propose that a combination of reflex anuria/ureteric edema and papillary sloughing led to the obstructive renal failure in both cases. Re-insertion of bilateral ureteric stents in case one, and replacement of a right ureteric stent in case two saw prompt excretion of urine and sloughy debris with rapid improvement of renal function. This article presents these cases in detail and further reviews the use of prophylactic ureteric stents in major abdomino-pelvic surgery along with the current guidelines for their usage.

Introduction: Access represents one of the main challenges in performing posterior urethroplasty (1, 2). Several approaches and tactics have been previously described (3). This video demonstrates the Anterior Sagittal Transrectal Approach (ASTRA), which allows better visualization of the deep perineum (4). Materials and Methods: Our patient was a 65-year-old man with post radical prostatectomy vesicourethral anastomotic stenosis. He failed repeated endoscopic interventions, eventually developing urinary retention and requiring a cystostomy. We offered a vesicourethral anastomotic repair through ASTRA. The patient was placed in the jackknife position and methylene blue instilled through the cystostomy. To optimize access to the bladder neck, an incision of the anterior border of the rectum is performed. Anastomosis is carried out with six 4-0 PDS sutures. These are tied using a parachute technique, after insertion of a 16F Foley. Results: The patient was discharged after 72 hours, and the Foley catheter was removed after 4 weeks. There were no access-related complications. Retrograde urethrogram 3 months after surgery confirmed patency of the anastomosis. Upon review 5 months after surgery the patient had urinary incontinence requiring 5 pads/day and was considered for an artificial urinary sphincter. Discussion: In our series of 92 patients who have undergone reconstructive procedure through ASTRA there have been no cases of fecal incontinence. Two patients with prior history of radiotherapy developed rectourethral fistulas. Urinary incontinence was observed in those patients with stenosis after radical prostatectomy. Conclusion: This video presents a step-by-step description of ASTRA, an approach that provides excellent visualization to the posterior urethra, representing an alternative access for repair of complex posterior urethral stenosis.
