LAPAROSCOPIC RESECTION OF LEIOMYOMA OF TRIGONE OF URINARY BLADDER

Summary

There are many cases of less common and rare diagnoses in medicine with no standardized guidelines and we have to try to take advantage of some therapeutic modality that is known from other more common diagnoses.

Case report (video):
A 42 y/o man, investigated for dysuria, on US, CT and 3T MRI was found to havea round mass 6cm in diameter in the bladder trigone. The finding was verified endoscopically and a biopsy under endoscopic control was taken using a “core” needle through the lower abdomen. Histology confirmed leiomyoma and surgery was planned. We intubated both ureters with single- loop stents using flexible cystoscope in supine position and introduced a urinary catheter. The patient was placed head down (Trendelenburg position). We used Veres needle for creation of pneumoperitoneum (12 mmHg), transumbilically introduced videotrocar 10 mm and under visual control other trocars – 2x5 mm and 1x11 mm. Transperitoneally at the base of the bladder we opened the posterior peritoneum transversally and urinary bladder longitudinally on the posterior wall. We used a harmonic scalpel during the surgery. The mass was gradually reflected from surrounding tissue including adjacent bladder wall. Both ureters (the left running along the mass) were freed. We sutured the trigone defect using V-Loc™ 90 3–0, the bladder wall with the same suture and then peritoneum with another suture. The operation time was 127 minutes with no blood loss. The specimen was extracted, histologically again evaluated as leiomyoma. We removed the urinary catheter after cystography on day 6 postoperatively. This man has now been 7 months after the surgery without any difficulty.

Conclusion:
Laparoscopy allows to treat even less common diagnoses, such as leimyoma localised on the bladder trigone.
