Comparative Study of Bacterial Isolation and Antibiotic Sensitivity Test of Urine and Catheter-tip Culture in Long-term Catheter Indwelling Patients / 대한비뇨기과학회지

Urinary tract infections constitute a large clinical problems that particularly affect catheter indwelling patients, causing morbidity and mortality. To investigate 1) the rate of infection by duration of catheter indwelling in patients of several kinds of disease, 2) the kinds of colonized bacteria and the similarity or difference of the bacterial species cultured in the urine and catheter of same patient, and 3) the comparison of sensitivity to antibiotics of cultured bacteria of both material, bacterial culture and antibiotic sensitivity test were done from urine and proximal tip of catheters in 31 catheter indwelling patients who had been administered, sometimes intermittently, various antibiotics. The rate of bacterial infection increased markedly with the lengthening of catheter indwelling period in urine and catheter cultures, 22.2% and 33.3% at 1 week, both 50% at 2-3 weeks, 78.6% and 85.7% at 4 weeks respectively The results of bacterial culture from both material were same in 27 (87.1%) patients. The gram negative bacteria composed of 41 (89.1%) species in cultured bacteria. The three frequent species were 16 (34.8%) Escherichia coli, 9 (19.6%) Klebsiella pneumonia, and 6 (13.0%) Morganella morgagni. The overall sensitivity of urine cultured bacteria to tested antibiotics showed minor difference from that of catheter, susceptible in 70.4%, and 73.8%, resistant in 28. 6%, and 24.6%, respectively. Almost all of the patients indwelling catheter longer than 4 weeks had bacterial infection or colonization in urine and proximal catheter-tip in spite of preventive administration of antibiotics. The urine culture only may be enough instead of culturing both the urine and proximal catheter-tip in long-term catheterized patients. Routine antibacterial drug administration should be taken into consideration not to be overused in long-term catheter indwelling patients.

A Case of Pelvic Abscess Due to the Perforated Appendicitis / 대한비뇨기과학회지

The pelvic abscess communicating with the appendix is relatively rare, however, it could be diagnosed preoperatively by various diagnostic modalities such as ultrasonography, computed tomography or laparoscopy. We experienced a case of pelvic abscess presented as a pelvic mass invading vesical wall, and report this unusual presentation with a brief review of literature.

Clinical Correlations between Transrectal Ultrasonographic Findings of the Seminal Vesicles and Ejaculatory Ducts, and Symptoms / 대한비뇨기과학회지

Transrectal ultrasonography provides an accurate assessment of the prostate, ejaculatory ducts and seminal vesicles, which can be helpful in the evaluation of the patients with variable genitourinary symptoms. We studied 65 symptomatic patients and 20 age-matched controls who underwent transrectal ultrasonography from Feb. 1993 to Jul. 1993. The broad spectrum of genitourinary signs and symptoms was segregated into 4 groups. Group 1 was hematospermia. Group 2 was pains including ejaculatory pain, pain on erection. perineal pain, scrotal pain, tenderness on prostate grand, suprapubic pain, lower back pain, inguinal pain, and penile pain. Group 3 was bladder outlet obstructive symptoms including hesitancy, intermittancy, terminal dribbling, weak stream, and residual urine sensation. Group 4 was bladder irritative symptoms including frequency, nocturia, urgency, and dysuria. The major abnormal findings on the transrectal ultrasonography were cysts in seminal vesicle, cysts in ejaculatory duct, prostatic calculi, ejaculatory duct calculi, and seminal vesicle dilation. Compared with age-matched controls, symptomatic patients had significantly increased prevalence of the abnormal findings on the transrectal ultrasonography (p <0.01 ). Ejaculatory duct calculi were significantly associated with bladder outlet obstructive symptoms and bladder irritative symptoms (p <0.05), and seminal vesicle dilation was also significantly associated with pain (p <0.05). Prostatic calculi and ejaculatory duct calculi were closely associated with voiding dysfunction, however, cyst in seminal vesicle and ejaculatory duct were closely associated with pain. Transrectal ultrasonography offers clinical insights into the causes of distressing genitourinary symptoms, and may be helpful in their management.
