Paolo Caione, Michele Innocenzi
This simple instrumentation may solve the problem of valve ablation in little infants. The advantages of the technique are its suitability in small neonates and the fact that it can be performed in areas of the world where pediatric endoscopic equipment is not easily available. However, a significant number of children have shown urethrorrhagia and periurethral extravasation of contrast in a postablation cystourethrogram.53

Increasing the number of cores in prostate biopsy decreases the probability of missing PCa diagnosis however has the potential risk of increasing the rate of complications including pain, hematuria, hematospermia, urethrorrhagia, rectal bleeding, and infection ranging from a simple urinary tract infection to sepsis [13]. Previous studies have reported that when the number of cores increased, significantly greater rectal bleeding and hematospermia were observed [14,15]. One overlooked fact is that a significant rate of older man having prostate biopsies has a tendency to bleeding because of anticoagulant or antiplatelet drugs. In these men, bleeding and other complications could become life threatening. Moreover, most patients are aware that the process is painful and their anxiety is likely to increase once they are informed about the complications. To avoid these, it is important to determine and if necessary, limit the optimal number of biopsy sites for each patient, taking into account age, PSA level, digital rectal examination (DRE) findings, and prostate volume (PV) [5,13].

As a sexually transmitted disease, genital warts are widely spread throughout the world. It can lead to the mucocutaneous intraepithelial neoplasia, which often occurs in the genital mucosa. The urethra is a hidden, warm and humid site for the HPV hiding and replicating at the same time. So the urethral genital warts tend to relapse. Up to now, there has been no large-scale epidemiological investigation about the incidence rate of urethral condyloma acuminatum. A report about 123 patients with urethral genital warts show that the incidence is 12.5% (9). Another research examined HPV-DNA of 463 healthy men reports that the urine samples were the poorest to detect with a rate of 10.1% among other genital sites (10). However, urethral condylomas are often combined with penile or vulva warts as well as urethritis, gonorrhea or other sexually transmitted infections. They mostly occur in people between 20 and 40 years old with high-risk behaviors. Patients complain of stinging, urethrorrhagia or dysuria when voiding (9). Some of them can find visible lesions in the distal urethra, such as the urethral meatus and navicular fossa places. But some others are not aware of suffering urethral meatus lesions (9). However, this does not rule out the possibility of genital warts. One of the reasons may be a latent infection, the other lies in that the warts can present in the upper urethra.
Factors affecting the diagnosis of prostate cancer through 12 quadrant guided prostate biopsy
Published in The Aging Male, 2020
TRUS-guided prostate biopsy has undesirable minor and major complications, including pain, rectal bleeding, urethrorrhagia, haematuria, haemospermia, and infection ranging from a simple urinary tract infection to sepsis [10,11]. Moreover, most patients are aware that the process is painful and their anxiety is likely to increase once they are informed about the minor and major risks of the procedure. To avoid these and other, similar problems during TRUS-guided prostate biopsy, it is important to determine the optimal number of biopsy sites for each patient, taking into account age, prostate-specific antigen (PSA) level, digital rectal examination (DRE) findings, and prostate volume (PV).
