In 5 procedures, it was not possible to advance the endoscope directly into the urethra, and thus, the cystoscope was advanced through the proximal urethra over a guide wire until the verumontanum
was visualized (Figure 1).
mucosal gland hyperplasia in prostatic needle biopsy specimens: amimic of low grade prostatic adenocarcinoma.

seviyesindeki kalsifikasyonlarin obstruksiyon sebebi olup olmayacagi konusunda halen tartismalar olmasina ragmen, ejakulator kanal obstruksiyonunu dusundurecek semen parametrelerine sahip olan olgularda, bu patolojilerin obstruktif patolojiler olarak degerlendirilmesi onerilmektedir.

Mullerian duct cysts do not communicate with the prostatic urethra, but are connected to the verumontanum
by a thin stalk.
In case 1, the patient had recurrent bladder cancer accompanied by metastatic urethral cancer and the urethral lesion was adjacent to the verumontanum
mucosal gland hyperplasia was present in 32 prostates (29%) (Table 1).
In normal anatomy, the verumontanum
or seminal colliculus is a protrusion found on the posterior wall of the prostatic urethra.
6-8] Like BPEPs, these tumors are often papillary and exophytic and are initially found in the prostatic urethra near the verumontanum
The routine surgical procedure started with an incision on both sides of the verumontanum
at the apex area.
Each procedure began by making an incision at the proximal part of verumontanum
from the 5 to the 7 o'clock positions.
This report focus on 5 peculiar cases in boys: a 4-year-old with a fibrovascular polypoid of the verumontanum
, a papilloma in a newborn, a hemangioma of the prostate in a 4-year-old, and 2 teenagers with papillary urothelial neoplasms of low malignant potential (PUNLMP).
