Penis

31.1K
The penis serves a dual role in sexual reproduction and urination. It consists of three main regions: the glans penis, the body, and the root, each with distinct functions and unique anatomical features.
Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...

Accessory Glands of the Male Reproductive System

The accessory ducts involved in sperm maturation and transportation include the epididymides, vasa deferentia, ejaculatory ducts, and urethra. These ducts play a critical role in the maturation, storage, and transportation of sperm from the testes to the urethra, where it is then released during ejaculation.
The epididymis is a small, comma-shaped organ located at the back of each testicle. The epididymis can be divided into three main parts: the head, body, and tail. The head of the epididymis...

Anatomy of the Genitourinary System II: Bladder and Urethra

2.0K
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

Male Sexual Response: Erection & Ejaculation

23.2K
Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

Urethra01:16

Urethra

4.9K
The urethra is a hollowed tubular organ through which urine is expelled from the body. This structure extends from the bladder to the external opening, allowing urine to be released.
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male...

Summary
This summary is machine-generated.

Penile cancer surgery now preserves more of the penis. A new technique, UCAPP, restores the urethral meatus position and creates a pseudo-glans after partial penectomy, improving cosmetic and psychological outcomes.

Area of Science:

  • Urology
  • Oncology
  • Plastic Surgery

Background:

  • Penile cancer management has shifted towards penile-preserving techniques.
  • Partial penectomy (PP) can result in abnormal urethral meatus position and stenosis.
  • Existing methods may compromise cosmetic and functional outcomes post-surgery.

Purpose of the Study:

  • To describe a novel technique (UCAPP) for urethral meatus centralization after PP.
  • To evaluate the creation of a pseudo-glans and wide meatus to maintain penile appearance.
  • To assess the impact of the technique on functional and psychological outcomes.

Main Methods:

  • The UCAPP technique involves urethral meatus centralization and pseudo-glans creation.
  • Split thickness skin grafting is utilized to reconstruct the glans.
  • The technique aims to restore normal meatal location and enhance cosmetic appearance.

Main Results:

  • The UCAPP technique successfully centralizes the urethral meatus post-PP.
  • Creation of a pseudo-glans and wide meatus is achieved.
  • Improved cosmetic appearance and reduced psychological morbidity are anticipated.

Conclusions:

  • The UCAPP technique offers a solution for post-partial penectomy penile reconstruction.
  • It addresses the challenges of abnormal meatal position and stenosis.
  • This approach can significantly improve patient quality of life after penile cancer surgery.
