Late-onset Hem-o-Lok® migration into the bladder after robot-assisted radical prostatectomy

A seed link connector protruding into the bladder formed a bladder stone

Introduction

Low-dose-rate brachytherapy is performed for localized prostate cancer. We report the first case of a bladder stone encompassing the seed migrated into the bladder in a patient treated with low-dose-rate brachytherapy.

Case presentation

A man was diagnosed with prostate cancer and underwent low-dose-rate brachytherapy. After 2 months, dysuria occurred, and ultrasonography revealed a needle-shaped high-intensity protruding from the prostate into the bladder. Cystoscopy examination found a seed link connector. With the possibility of natural dissolution of the seed link, careful observation was chosen. However, 16 months later, hematuria occurred, and an X-ray revealed a bladder stone encompassing the seed. Compared with the X-ray right after seeding, the seed located near the right bladder neck had fallen. The seed was removed by transurethral bladder lithotripsy.

Conclusion

Seeds should be carefully located within the prostate, otherwise a bladder stone may be formed encompassing the seed.

Type II Hem-o-lok clip migration and stone formation in robot assisted laparoscopic prostatectomy patient: A case report and serial cases review

Hem-o-lok clips (HOLC) migration after laparoscopic surgery may cause delayed postoperative issues. We present a delayed lower urinary tract symptoms (LUTS) and urinary stones due to HOLC migration from previous radical prostatectomy approximately 10 years ago. A 88-year-old man presenting clinic with LUTS; previously received robotic-assisted laparoscopic radical prostatectomy (RALP) 10 years ago. HOLC and stones from the bladder were extracted with cystoscopy lithotripsy. Latest follow-up noted complete resolution of symptoms. RALP may cause HOLC migration with variable duration of LUTS symptoms occurring, reaching up to 10 years.
