Summary
Menstrual cups can cause rare but serious complications like ureterohydronephrosis. Prompt removal of the device led to symptom resolution, highlighting the need for user and clinician awareness.
Area of Science:
- Urology
- Gynecology
Background:
- Menstrual cups are popular for managing menstrual bleeding.
- Serious complications are rarely documented but can occur.
Purpose of the Study:
- To report a rare case of ureterohydronephrosis caused by a menstrual cup.
- To increase awareness of potential menstrual cup complications.
Main Methods:
- Case report of a woman in her 30s.
- Diagnostic imaging including CT urography and ultrasound.
- Clinical assessment before and after intervention.
Main Results:
- A menstrual cup was found causing obstruction near the right ureteral opening.
- Ureterohydronephrosis was diagnosed.
- Symptoms and ureterohydronephrosis resolved completely after menstrual cup removal.
Conclusions:
- Menstrual cup use can lead to rare genitourinary complications.
- Proper selection of size, shape, and insertion technique is crucial.
- Clinicians and users need increased awareness of potential symptoms and risks.

01:20Disorders of the Urinary System
223
The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

01:22Ureters
322
The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...

01:23Urinary Bladder
331
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...

01:24Physiology of Urine Formation
2.8K
Urine formation is an essential function of the human body. It plays a critical role in maintaining homeostasis by regulating the volume and composition of body fluids. The kidneys, the primary organs involved in this process, filter blood to remove waste products and excess substances, ultimately producing urine.
Glomerular Filtration
The first stage in urine formation is glomerular filtration. Each kidney contains approximately 1 million nephrons, the functional units of filtration, with a...

01:20Formation of Dilute Urine
1.2K
The formation of dilute urine is a critical renal adaptation that maintains fluid balance, particularly during periods of high fluid intake. This process primarily involves the juxtamedullary nephrons. By adjusting the permeability of water and ions in response to physiological conditions, the kidneys can either conserve or excrete water, resulting in concentrated or dilute urine.

01:24Renal Tubule and Collecting Duct
734
The renal tubule is divided into three parts: the proximal convoluted tubule (PCT), the Loop of Henle (LOH), and the distal convoluted tubule (DCT).
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
