Urinary Bladder01:23

Urinary Bladder

4.7K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

Urethra01:16

Urethra

7.1K
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...

Anatomy of the Genitourinary System II: Bladder and Urethra

3.7K
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...

Uterine Tubes01:16

Uterine Tubes

4.2K
The uterine or fallopian tubes function as the conduit through which oocytes travel from the ovaries to the uterus. Each fallopian tube measures approximately 10 to 13 cm long and is anatomically divided into the infundibulum, ampulla, isthmus, and interstitial part (or intramural segment). The infundibulum is characterized by its funnel shape and features extensions called fimbriae which reach towards the peritoneal cavity. These fimbriae play a critical role during ovulation as they extend...

Appendicitis01:19

Appendicitis

33
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...

Histology of the Uterus01:19

Histology of the Uterus

5.1K
The uterine wall consists of three histological layers: the perimetrium, myometrium, and endometrium. The outermost perimetrium is a thin, serous membrane connected with the broad ligament on the sides, which helps anchor the uterus in the pelvic cavity. The thickest layer, myometrium, is mainly made up of smooth muscle tissue bundles. Its contractions are vital in facilitating the expulsion of the uterine lining, fetus, and placenta during menstruation and childbirth.
The endometrium is the...

Summary

Paraurethral leiomyomas are benign smooth muscle tumors. Surgical resection offers a favorable long-term outcome with no recurrence, as demonstrated in this case study.

Area of Science:

  • Urology
  • Gynecologic Oncology
  • Pathology

Background:

  • Paraurethral leiomyomas are rare benign tumors originating from the smooth muscle of the urethra or vagina.
  • Understanding their clinical presentation and diagnostic modalities is crucial for effective management.

Observation:

  • This case report details a patient with a paraurethral leiomyoma.
  • Preoperative diagnostic procedures and clinical manifestations were evaluated.

Findings:

  • The paraurethral leiomyoma was successfully resected.
  • The patient remained asymptomatic with no recurrence six years post-surgery.

Implications:

  • Paraurethral leiomyomas are confirmed as benign entities with successful surgical outcomes.
  • Magnetic resonance imaging (MRI) can aid in preoperative tumor localization, but histological confirmation remains definitive for diagnosis.
