Transvaginal bladder neck suspension of raz technique for stress urinary incontinence / 대한비뇨기과학회지

Bladder dysfunction after radical rectal cancer surgery has been well known but there has not been sufficient objective data in Korea. We performed consecutive urodynamic study preoperatvely, postoperative tenth day and postoperativesixth month on 71 patients undergone radical rectal surgery. Compared with preoperative state. each urodynamic parameters changed significantly : maximal flow rate and average flow rate decreased ; voiding sense and residual urine volume increased ; bladder capacity, compliance and detrusor pressure decreased ; and maximal urethral pressure, functional urethral pressure and functional urethral length changed. All in all, we came out with the results that autonomic denervation was developed in 59 (83%) out of 71 in postoperative tenth day and 11 (28%) out of 39 in postoperative sixth month. Except for the residual urine volume and detrusor pressure, no significant recovery was observed in postoperative sixth month. Univariate analysis showed that sex, age, tumor size, distance from anal verge, stage, intraluminal tumor position and mode of operation had no significant influence on urodynamic parameters. However, the higher the stage, the more damages were found in multivariate analysis using logistic regression with correction of sex and age. Bladder dysfunction after rectal cancer operation is caused by partial autonomic denervation where urologic care is necessary, however as a whole, bladder dysfunction is considered to be a temporary change.

A clinical evaluation of urethral stricture / 대한비뇨기과학회지

The results with management of urethral stricture are disappointing, with a high rate of early and late recurrence. Recently, the success of internal urethrotomy has made us question the role of open urethroplasty in the management of urethral strictures. Thus a clinical evaluation was made on 116 patients with urethral stricture in the Department of Urology, Masan Koryo General Hospital, during the period from May 1985 to July 1991. The or stricture was incomplete in 92 cases and complete in 24 cases. The length of stricture was less than 1cm in 86 cases, 1 to 2cm in 19 cases, more than 2cm in 3 cases and multiple strictures in 8 cases. The treatment modality of incomplete urethral stricture was internal urethrotomy in 68 cases and urethroplasty in 9 cases regardless of length, and dilatation in 15 cases with mild stricture. Incomplete urethral stricture, internal urethrotomy was carried out in 7 cases with less than 1cm long stricture and urethroplasty in 17 cases regardless of length. The overall success rate in incomplete urethral stricture was 88.2 % in internal urethrotomy and 88.9 % in urethroplasty, and in complete urethral stricture, 85.7 % in internal urethrotomy and 82. 4% in urethroplasty. We think that visual internal urethrotomy is a valuable initial method, when stricture is incomplete or less than 1cm in length in cases of complete urethral stricture.

A case of liposarcoma of spermatic cord / 대한비뇨기과학회지

Liposarcoma of the spermatic cord is a rare tumor. Most are of a low-grade malignancy and recurrences tend to be localized. Preoperative diagnosis is difficult. Wide local excision with radical orchiectomy appears to be adequate treatment. A regional lymph node dissection is usually not advocated since the pattern of spread is hematogenous. We report a case of liposarcoma of the spermatic cord in 49-year-old male with brief review of the literatures.
