Clinical Scorecard: Assessment of Surgical Practices in Renal Transplantation: Insights from Urological and Surgical Centers Across Germany

At a Glance

Key Highlights

• 38 certified kidney transplant centers in Germany with 89.5% response rate to survey (13 urology-led, 21 surgery-led).
• Majority of transplants performed via open extraperitoneal approach; robotic-assisted laparoscopic transplants more common in urology-led centers.
• Significant differences in perioperative practices such as BMI limits, donor organ retrieval methods, vascular and ureteral anastomosis techniques, and postoperative catheter removal timing.

Guideline-Based Recommendations

Diagnosis

• Preoperative patient preparation generally similar across centers; nicotine cessation and weight normalization not mandatory in majority.
• BMI limits vary significantly between urology-led and surgery-led centers.

Management

• Open extraperitoneal kidney transplantation via hockey stick incision is standard; robotic-assisted laparoscopic approach used selectively.
• Donor organ retrieval for living donation predominantly minimally invasive, more frequent in surgery-led centers.
• Vascular anastomosis mostly performed with 5-0 or 6-0 prolene sutures; continuous front and back suturing preferred by urologists, parachute technique more common in surgeons.
• Ureteral implantation mainly via Lich-Gregoir technique; suture material varies between centers.
• Perioperative insertion of ureteral stents and bladder catheters is standard.
• Postoperative care often on intermediate care wards; urology-led centers more likely to manage postoperative care within operating department.
• Bladder catheter removal occurs earlier in surgery-led centers (<7 days) compared to urology-led centers (7–10 days).
• Discharge timing varies, with surgery-led centers discharging earlier (6–8 days) than urology-led (10–14 days).
• Management of complications such as urinary tract dilation and symptomatic lymphoceles includes stent insertion, drainage, and minimally invasive fenestration.

Monitoring & Follow-up

• Postoperative monitoring on intermediate care wards or via interdisciplinary concepts depending on center leadership.
• Close monitoring of urinary tract dilation and lymphocele development with appropriate interventions.

Risks

• Potential risks include lymphocele formation, urinary reflux, and complications related to vascular and ureteral anastomoses.
• Differences in surgical technique and postoperative management may influence complication rates.

Patient & Prescribing Data

Kidney transplant recipients in German transplant centers, including adult and pediatric patients

Standard perioperative and postoperative protocols include use of ureteral stents and bladder catheters; timing of catheter removal and discharge varies by center leadership.

Clinical Best Practices

• Perform kidney transplantation predominantly via open extraperitoneal approach with hockey stick incision.
• Use minimally invasive donor organ retrieval techniques for living kidney donation when feasible.
• Apply continuous front and back suturing technique for vascular anastomosis, especially in urology-led centers.
• Utilize Lich-Gregoir technique for ureteral implantation with appropriate suture material.
• Insert perioperative ureteral stents and bladder catheters routinely.
• Manage postoperative care on intermediate care wards with interdisciplinary collaboration where possible.
• Remove bladder catheters between 7–10 days postoperatively in urology-led centers and earlier (<7 days) in surgery-led centers based on patient condition.
• Discharge patients typically between 10–14 days post-transplant, adjusting for clinical status.
• Address complications such as urinary tract dilation and lymphoceles promptly with stenting, drainage, or minimally invasive fenestration.
• Consider center-specific protocols and surgeon expertise when planning surgical and postoperative management.
