Chlamydia trachomatis-induced urethritis in female partners of men with nongonococcal urethritis.

The rate of isolation of Chlamydia trachomatis from cervical and urethral specimens from 99 culture-positive female partners of men with nongonococcal urethritis who were attending a gynecological outpatient clinic was correlated with the clinical status of the women. The agent was recovered from both sites in 46 women, from the cervix only in 28, and from the urethra only in 25 women. Urethral symptoms were reported by 38 (54%) of those with positive urethral cultures, as compared with six (21%) of those with positive cervical cultures only (P less than 0.01). Significant bacteriuria was found in only three patients with urethral symptoms; two of them had negative urethral cultures for C. trachomatis. Frequencies of cervicitis, rises in titer of antibody, and geometric mean titers of immunofluorescent antibody to C. trachomatis did not differ significantly among the three groups.

Persistent urethral leukocytosis and asymptomatic chlamydial urethritis.

Chlamydia trachomatis was isolated from 47% of asymptomatic, sexually active men whose urethral smears contained four or more polymorphonuclear leukocytes (PMN) per high-power field (hpf) one week after their sexual activity was restricted. C. trachomatis was not detected in any of 23 asymptomatic, sexually active men having less than 4 PMN/hpf in two urethral smears obtained one week apart. Semiquantitation of urethral PMN in the urethral Gram-stained smear is useful in the evaluation of asymptomatic men without gonorrhea who are concerned about the possibility of harboring a urethral pathogen.

Infection of a nonspecific urethritis patient and his consort with a pathogenic species of nonspecific urethritis Corynebacteria, Corynebacterium genitalium, N. SP.

A patient with nonspecific urethritis (NSU) and his consort were examined for infection with NSU corynebacteria, mycoplasmas, and gonococci. No classic and T-mycoplasmas or gonococci were cultured, but one species of NSU corynebacteria was isolated not only from the patient's urethral discharge during three episodes of NSU but also from his consort. It was not isolated after successful treatment of the patient with tetracycline and the use of condoms prevented reoccurrence of urethritis. This NSU corynebacterium was isolated previously from one epididymitis patient and two NSU patients but not from any of the normal male and female subjects examined. Therefore, this strain is considered to be one of the etiologic agents of NSU and female subjects are asymptomatic carriers. In consequence, it is suggested that NSU corynebacteria which are commensals and pathogens of the male and female urogenital tracts should be incorporated in a new species, of the Coryneform group, and that this strain should be the type species, Corynebacterium genitalium n. sp.

Urethral pressure profilometry: assessment of urethral function by combined intraurethral pressure and electromyographic recording.

The technique of combined electromyographic and carbon dioxide urethral pressure profilometry is described and analyzed. The low viscous drag of carbon dioxide permits the use of catheter infusion rates above the critical threshold, where the compressibility of the gas does not influence the accuracy of the pressure recording. Clinical urethral function studies with this technique in benign prostatic hypertrophy, stress incontinence and traumatic spinal cord injury have documented the diagnostic value of the test. Furthermore, the impact of surgical or pharmacological treatment upon urethral function has been delineated.

Urethral pressure profile in children: a comparison between perfused catheters and micro-transducers, and a study of the usefulness of urethral pressure profile measurements in children.

Urethral pressure profiles were done on 46 children by the classical open-end perfused catheter and by a micro-transducer mounted on the tip of a catheter. A comparative study of the results obtained using the 2 methods demonstrates clearly the superiority of the micro-transducer over the perfused catheter. There are so many limitations of precison with the perfused catheter method that its usefulness for clinical studies seems questionable. With both methods the urethral pressure profile alone was not sufficient for distinguishing betweeen obstructed and non-obstructed bladder outlets.

Effect of urethral stretch on urethral pressure profile.

Urethral pressure profiles were recorded in anesthetized dogs with the urethra in both the relaxed and stretched positions. Similar studies were done with fresh specimens of intact dog bladder and urethra removed en bloc. Clinical studies were performed on women during surgical correction of stress incontinence. The pressure profiles reflected the intrinsic smooth muscular activity of the urethra, inasmuch as they were all obtained under full relaxation by anesthesia and with the abdomen open. In all cases, functional as well as anatomical lengths of the urethra were increased with stretch. The rise in urethral closure pressure was most marked in the proximal third of the urethra. Changes were more notable in women with stress incontinence than in the normal dog. Similar results were noted in the in vitro studies. Length-tension properties of smooth and striated muscles offer a clear explanation for the rationale and effectiveness of surgical procedures done for the correction of stress incontinence.
