Abstract

(Purpose) Transurethral electrocoagulation (TUC) is a rare event but occurs in a constant manner with various causes or disorders and reduces patient quality of life. So far there have been no reports focusing on the details of TUC. We focused on the clinical background and related causes in cases of TUC in our institution. (Patients and methods) We identified 76 cases (65 patients) who underwent TUC at Keio University Hospital between April 2001 and March 2011. We focused on patient background, especially with respect to the primary disease, treatment modality, use of antiplatelet or anticoagulant agent, timing of TUC, type of electrosurgical device, and the incidence of transfusion. (Results) The primary disease for TUC included bladder tumor (BT) in 31 cases, benign prostate hyperplasia (BPH) in 13, prostate cancer (PCa) in 13, idiopathic bladder bleeding in 4, periarteritis nodosa in 3, uterine cervical cancer in 3, and others in 9. TUC after transurethral resection (TUR) was found in 38 cases, including transurethral resection of bladder tumor (TURBT) in 26 of 31 BT cases and transurethral resection of prostate (TURP) in 12 of 13 BPH cases. After TURBT, TUC was performed before removal of a urethral catheter in 7 cases, and after removal of a urethral catheter in 19 cases. With regard to TUC associated with TURP, the average estimated prostate volume in TUC cases before removal of the urethral catheter was 66.2 ml, which was significantly larger than that in TUC cases after removal of the urethral catheter (46.1 ml, p = 0.045). TUC after the radiation therapy was observed in 21 cases, and the average time from the radiation therapy to TUC was 3.4 years (7 months-10 years). (Conclusion) TUC was caused by multiple causes or disorders, and 75% of our TUC was associated with BT, BPH or PCa. TUC associated with TURBT frequently occurred within 1 week after TURBT but was still observed after 1 month following the operation. All TUC associated with TURP occurred within 3 weeks after operation. The average period from radiation therapy to TUC was 3.4 years (7 months-10 years) and TUC associated with radiation cystitis could occur beyond 5 years after radiation.
