Objective   To find the novel treatment method of severe seminal vesicle (SV) disease and hemospermia for those who fail to respond to other treatment modalities.    Methods   Five patients at the age of 48  to 77 (mean 55.4)

who had significant symptoms of SV disease and hemospermia for 4 to 10 years that failed to respond to conservative treatment

underwent transurethral electro-resection or electric cauterization of SV through extra- or intra-seminal vesicle approach.    Results   Transurethral electro-resection or electric cauterization of SV was successfully performed for the 5 patients. The operation time was 50 to 65 min and the amount of blood loss in patients was 20 to 50 ml. No complication occurred during or after operation. Pathological examination after operation showed non specific chronic inflammation in the resected SV tissue. The patients were followed up for 4 to 12 months

during which their pre-operation symptoms disappeared and their sexual life was recovered with hedonia.    Conclusion   As a brand-new procedure

minimally invasive transurethral electro-resection of SV can be performed for those with severe SV disease which fails to respond to conservative treatment.
