Primary Amyloidosis of the Bladder / 대한비뇨기과학회지

Amyloidosis is a systemic disease characterized by the deposition of homogenous, eosinophilic and hyaline protein. Most cases of amyloidosis occur as a systemic disease, with a poor prognosis. Conversely, primary localized amyloidosis of the bladder has an excellent prognosis in most cases, it is, therefore, important to distinguish primary localized from systemic amyloidosis. Primary localized amyloidosis of the bladder is a rare disease, causing hematuria, which is often confused with bladder cancer. The diagnosis is usually made from a biopsy and subsequent pathological examination. We report a case of primary localized amyloidosis of the bladder, occurring in a 73 year old man, treated with a transurethral resection.

A Comparative Study of Visual Internal Urethrotomy and Perineal Urethroplasty in the Treatment of Posttraumatic Urethral Strictures / 대한비뇨기과학회지

The outcomes of treatment of 31 patients who were managed by single visual internal urethrotomy were compared with those of 25 patients managed by perineal urethroplasty to asses whether the replacement of almost urethroplasty by the simpler urethrotomy was justified. The overall successful results were achieved in 51.6% of visual internal urethrotomy and 76%, of urethroplasty. Patients with anterior urethral strictures more than 1 cm long or completely obliterated strictures had higher failure rates in the visual internal urethrotomy than urethroplasty (p<0.05). The morbidity rates were 9.6% in the visual internal urethrotomy and 24% in the urethroplasty. We recommend that visual internal urethrotomy be reserved for patients with urethral strictures 1 cm or less in length and posterior urethral stricture which is supposed to have a high recurrence rate since the procedure is simple and it does not compromise asecondary urethroplasty.
