Abstract

Background: Robotic-assisted laparoscopic prostatectomy (RALP) is the most preferred intervention for the management of prostatic malignancy worldwide. Hem-o-Lok clips (HOLC) are widely used for haemostasis and lateral pedicle ligation. These clips are prone to migrate and lodge at the anastomotic junction as well as inside the bladder causing lower urinary tract symptoms (LUTS) secondary to bladder neck contracture (BNC) or bladder calculi. The objective of this study is to describe the incidence, clinical presentation, management, and outcome of HOLC migration.

Methodology: Retrospective analysis of the database of Post RALP patients who developed LUTS secondary to HOLC migration was done. Cystoscopy findings, number of procedures required, number of HOLC removed intra-operatively, and follow-up of the patients was reviewed.

Results: The incidence of HOLC migration requiring intervention was 1.78% (9/505). The mean age of the patient, BMI, Pre-operative Serum PSA were 62.8 years, 27.8 kg/m2, and 9.8 ng/mL, respectively. The mean duration of appearance of symptoms due to HOLC migration was 9 months. Two patients presented with Haematuria and 7 presented with LUTS. Seven patients required a single intervention while 2 required up to 6 procedures for recurrent symptoms secondary to recurrent HOLC migration.

Conclusion: HOLC use in RALP may present with migration and associated complications. HOLC migration is associated with severe BNC and may require multiple endoscopic interventions. Severe dysuria and LUTS not responding to medical management should be treated using an algorithmic approach and there should be a low threshold for performing cystoscopy and intervention in these cases to improve outcomes.
