Prostate biopsy sepsis prevention: external validation of an alcohol needle washing protocol.

PURPOSE: Transrectal ultrasound-guided prostate biopsy (TRUS-Bx) is associated with a 1-8% risk of post-biopsy sepsis (PBS). A recent study described an isopropyl alcohol needle washing protocol that significantly decreased PBS rates. The current study examined the efficacy of this technique in our clinic population. MATERIALS AND METHODS: Data were reviewed for 1250 consecutive patients undergoing TRUS-Bx at the Charlie Norwood VA Medical Center from January 2017 to January 2023. Needle washing was adopted in February 2021. Complications occurring within 30 days after TRUS-Bx were recorded. RESULTS: There were 912 patients in group 1 (without needle washing) and 338 in group 2 (with needle washing). Groups had equivalent demographic features, and men of African descent comprised 70% of patients. Standard 12 core biopsies were done in 83% and 82% in groups 1 and 2, respectively (p = 0.788). Total complication rates were 4% and 2% in groups 1 and 2, respectively (p = 0.077). There were 13 sepsis events in group 1 (1.4%) and none in group 2 (p = 0.027). Clavien-Dindo Grade I-III complications occurred in 25 (2.7%) and 7 (2.1%) patients in groups 1 and 2, respectively (p = 0.505). Standard antibiotic prophylaxis (PO fluoroquinolone and IM gentamicin) was given in 80% and 86% of patients in groups 1 and 2, respectively (p = 0.030). Subset analysis limited to patients who received standard prophylaxis showed a significant difference in sepsis rates (1.5% vs 0%; p = 0.036). CONCLUSIONS: Adoption of isopropyl alcohol needle washing was associated with a significant decrease in PBS events.

Suspension of Oncology Randomized Clinical Trials during the COVID-19 Pandemic: A Cross-Sectional Evaluation of COVID-Related Suspensions.

We conducted a cross-sectional analysis of ClinicalTrials.gov-registered oncology randomized controlled trials between September 2019 and December 2021 to identify predictors of trial suspensions. The dataset included 1,183 oncology trials, of which 384 (32.5%) were suspended. COVID-19 accounted for 47 (12.2%) suspensions. Trials that were single center- or US-based had higher odds of COVID-19 (ORs: 3.85 and 2.48, 95% CIs: 1.60-11.50 and 1.28-4.93, respectively) or any-reason suspensions (ORs: 2.33 and 2.04, 95% CIs: 1.46-3.45 and 1.40-2.76, respectively). Phase two (OR 1.27), three (OR 6.45) and four trials (OR 11.5) had increased odds of COVID-19 suspensions, compared to phase one trials.

Massive Chylous Ascites After Living Donor Nephrectomy Successfully Treated With Lymphatic Embolization.

Chylous ascites may result from a variety of pathological conditions, most of them from nontraumatic causes, such as congenital defects of the lymphatic system, infections, liver cirrhosis, and malignancy. Rarely, chylous ascites occurs as an iatrogenic complication after left-sided laparoscopic donor nephrectomy (LDN). Injury to the cisterna chyli and its main lymphatic tributaries around the para-aortic region intraoperatively can cause the lymphatic fluid to accumulate. There is currently no standardized treatment for chylous ascites as there have only been 54 cases documented to date. Most patients can be managed with conservative therapy. Recommended guidelines include high-protein and low-fat diet with medium-chain triglycerides. Paracentesis is often used as a diagnostic and therapeutic first-line measure with total parenteral nutrition (TPN), bowel rest, and somatostatin analogue as adjunct therapies. We present a case of massive chylous ascites refractory to conservative therapy. The patient had progressive abdominal distention and unintentional weight gain 2 weeks postoperatively warranting multiple paracenteses of >7 L of chylous fluid. Ultimately, the patient was successfully treated with lymphatic embolization using N-butyl cyanoacrylate glue.

Early Experience with Salvage Retzius-sparing Robotic-assisted Radical Prostatectomy: Oncologic and Functional Outcomes.

OBJECTIVE: To report on feasibility, safety, and continence outcomes using the Retzius-sparing approach in the salvage setting (sRS-RARP). MATERIALS AND METHODS: A total of 26 patients underwent robotic salvage prostatectomy at our institution from January 2012 to May 2020 by a single surgeon (RM). Twenty patients underwent sRS-RARP and 6 underwent the standard approach (sRARP). Pre-, intra-, and postoperative outcomes were compared between these groups with emphasis on continence and oncologic safety. RESULTS: Patients had comparable preoperative characteristics with no significant difference in age, race, prostate-specific antigen level, and Gleason score. Most patients underwent primary external beam radiation therapy (69.2%). Median time to biochemical failure was 7.9 years (IQR 6.1-13.4). sRS-RARP required less console time (141.5 vs 199.5.0 minutes, P = .008) and less blood loss (50.0 mL vs 100.0 mL, P = .045) compared to sRARP. Postoperative course was uneventful with a median hospital stay of 1 day. Median catheterization time was 14.0 days (IQR 11.5-17). Patients undergoing sRS-RARP had better immediate (25.0% vs 0.0%, P < .001), 3 month (80.0% vs 0%, P < .001), and 12 month continence rates (100% vs 44%, P = .0384) compared to sRARP patients. Likewise, median time to continence was significantly shorter for sRS-RARP patients (90.0 vs 270.0 days, P = .0095). Biochemical recurrence rate was 20.0% in the sRS-RARP group and 33.3% in the sRARP group (P = .60). CONCLUSION: Early experience suggests that sRS-RARP is feasible, oncologically safe, and may offer improved continence compared to the sRARP approach.
