How should an adult male be managed during the first five days after Aquablation, regarding catheter removal, pain control, antibiotics, hydration, activity restrictions, and warning signs?

Post-Aquablation Management: First 5 Days

Catheter removal should occur on postoperative day 1 after a successful voiding trial, though patients with preoperative acute urinary retention have a 40% failure rate on initial trial and may benefit from delayed catheter removal. 1

Catheter Management

• Remove the Foley catheter on postoperative day 1 for uncomplicated cases to minimize infection risk and patient discomfort. 2

• Patients with preoperative acute urinary retention require special consideration: 40% will fail their initial voiding trial compared to only 7.2% of patients without retention, suggesting these patients may benefit from a delayed trial without catheter. 1

• Patients with chronic retention (postvoid residual >300 mL) have a 12.5% failure rate on initial voiding trial, intermediate between acute retention and no retention groups. 1

• Monitor for urinary retention after catheter removal: Check postvoid residual if patient reports incomplete emptying or has difficulty voiding. 2

• If voiding trial fails, replace catheter and retry in 24-48 hours; intermittent catheterization every 4-6 hours is an alternative if postvoid residual exceeds 100 mL. 2

Bleeding Management and Monitoring

• Bleeding is the primary concern in the first 5 days: Historical rates approached 8.3% with catheter traction as the predominant hemostatic technique, but systematic cautery loop hemostasis has reduced this to 1.4%. 3

• Transfusion rates remain at 2.7% in real-world multi-center experience, with mean hemoglobin drop of 2.06 g/dL. 4, 5

• Monitor for hematuria: Mild hematuria is expected initially but should progressively clear. Heavy bleeding with clots, inability to void, or hemodynamic instability requires immediate urologic consultation. 3

• Maintain adequate hydration to prevent clot formation and facilitate bladder irrigation if needed. 2

Pain Control

• Use multimodal analgesia: Acetaminophen and NSAIDs are first-line agents for postoperative pain control. 2

• Avoid opioids if possible due to constipation risk and other complications, particularly in the setting of recent prostate surgery. 2

• Bladder spasms are common: Anticholinergic agents may help with bladder spasm discomfort, though use cautiously to avoid urinary retention. 2

• Local measures: Cool packs applied to the perineum and topical anesthetic sprays can provide additional relief. 2

Antibiotic Management

• Prophylactic antibiotics are not routinely continued beyond the perioperative period unless specific infection risk factors exist. 2

• Monitor for urinary tract infection: Fever, dysuria, or change in mental status should prompt urinalysis and culture. 2

• Indwelling catheters increase UTI risk significantly: This is another reason for early catheter removal on day 1. 2

• If UTI develops, treat with appropriate antibiotics based on culture results. 2

Activity Restrictions

• Early mobilization is encouraged once hemodynamically stable to prevent complications including atelectasis, pneumonia, and venous thromboembolism. 2

• Avoid heavy lifting (>10 pounds) and strenuous activity for 2-4 weeks to minimize bleeding risk. 6

• Sexual activity can resume at 1-2 weeks if patient can perform mild to moderate physical activity without symptoms, though this extends beyond the initial 5-day period. 6

• Encourage regular walking to promote recovery and prevent complications from immobility. 2

Bowel Management

• Implement bowel program immediately: Constipation increases intra-abdominal pressure and bleeding risk. 2

• Stool softeners should be started prophylactically rather than waiting for constipation to develop. 2

• Ensure adequate fluid and fiber intake to maintain soft stools. 2

• Avoid straining with bowel movements: This can precipitate prostatic bleeding. 2

Warning Signs Requiring Immediate Attention

• Heavy bleeding with clots or inability to void: May require catheter reinsertion, irrigation, or return to operating room. 3, 7

• Fever >38.5°C (101.3°F): Evaluate for UTI, pneumonia, or other infection sources. 2

• Inability to void after catheter removal: Check postvoid residual and consider catheter replacement. 2, 1

• Severe pain uncontrolled by oral medications: May indicate bladder spasm, clot retention, or other complication. 2

• Signs of sepsis: Confusion, hypotension, tachycardia with fever require emergency evaluation. 2

Hospital Readmission Risk

• Patients undergoing Aquablation have higher 30- and 90-day readmission rates compared to other BPH procedures, potentially related to the learning curve or application to larger prostate volumes. 7

• Catheter reinsertion is more common in Aquablation patients at 30 and 90 days postoperatively compared to most other surgical BPH cohorts. 7

• Close follow-up is essential: Schedule early postoperative visit within 1-2 weeks to assess voiding function and address complications. 2, 7
