“… 2 Rare cases of renal colic have been reported, caused by a menstrual cup blocking the urinary tract. 21 – 23 These could be attributed to menstrual cups being too large or firm and exerting pressure on the tissues surrounding the vagina. Similarly, a case of hydroureteronephrosis (blockage leading to kidney breakdown) was caused by ‘deeply inserted’ menstrual cup suctioning on the fornix (the recess from the protrusion of cervix).…”

Objectives: Menstrual cups come in a range of shapes, sizes, and firmnesses, but unlike tampons are not categorized in any way. With these factors having an impact on product leaks and comfort, as well as being linked to illness and injury, women need the same level of transparency when purchasing a menstrual cup. The comparison of physical and mechanical properties of menstrual cups will be the first step to achieve this. Methods: In October 2020, 14 popular and highly rated menstrual cups underwent quantitative comparison in laboratory settings (the United Kingdom), and they were compared in terms of their dimensions, volume, and compressive strength (firmness) using the Instron Universal Testing System. The overall designs were compared including shape, material, and features. Results: Although all the products in this comparison were marketed to women below 30 years of age having never given birth, total volume varied from 18.88 mL to 38.14 mL, and compressive load to compress the menstrual cup 50% (±0.5%) maximum diameter varied from 3.39 N to 13.92 N. Conclusions: Women are not sufficiently informed when choosing a menstrual cup. With no correlation between menstrual cup size, shape, and its volume, or material, shape, and its firmness, consumers cannot estimate which menstrual cup might be most suitable, and incorrect choice could cause injury. Transparency is needed across menstrual cup brands. With this and further regulation, women will make an informed decision to choose the correct menstrual cup and minimize injury. This work recommends firmness categories, ranging from ‘very soft’ to ‘very firm’ as a first step.

“…Rare case reports on renal colic and hydronephrosis in individuals using a menstrual cup have been published. [36][37][38][39][40] Menstrual cup placement may be facilitated by using a reusable device similar to a tampon applicator, wherein a folded cup is placed into a cylinder with a plunger (Fig. 2).…”
