[Anatomic observation of the prostate for clinical application of local drug injection through the rectum for chronic prostatitis].

OBJECTIVE

To provide anatomic evidences for local drug injection through the rectum for treating chronic prostatitis and observe the therapeutic effect of this treatment.

METHODS

Anatomic observation of the median sagittal plane of 16 male pelvic specimens was conducted, with special attention to the structures between the prostate and the rectum. The distance from the posterior wall of the prostate to the anterior wall of the rectum, the scope that allowed the entry of the puncture needle, the appropriate puncture depth, and the distance from the anus to the safe were carefully measured. Analysis of the clinical record was performed in 51 chronic prostatitis cases treated with local injection of prednisolone, antibiotic and lidocaine through the rectum.

RESULTS

Only some fat tissues and venous plexus were found between the prostate and the anterior wall of the rectum, and the distance from posterior wall of the prostate to the anterior wall of the rectum averaged 5.773+/-0.710 mm. The scope for possible puncture was 15.408 8+/-1.438 2 mm with a depth of 15.703 1+/-0.944 1 mm. The maximum and minimum distances from the anus to the puncture were 47.594+/-2.432 mm and 35.781+/-1.850 mm, respectively. Among the 51 cases investigated, the total cure rate was 84.31%, and improvement was achieved in 13.73% of the case, with only one case (2%) failed to respond to the treatment.

CONCLUSION

Local drug injection through the rectum can be ideal for the treatment of prostatitis for its safety and effectiveness.
