Vesical calculus: An unusual cause of labour dystocia

A Giant Vesical Stone Causing Impending Rupture of Bladder During Labor

“…However, when it is diagnosed in early labor before the engagement of fetal head, vaginal delivery can be possible if the stone is pushed above the head [17]. If the stone is neglected, then it can be trapped between symphysis pubis and fetal head causing arrest of fetal descent, dystocia of labor [2,4,6,[10][11][12][13][14][15][16][17][18]. Rarely, the stone becomes dislodged and comes in front of fetal head.…”

“…Available evidence shows that 5 % of all urinary stones are found in urinary bladder, and approximately 5 % of all BS occur in women [3]. Due to rarity and unfamiliar condition during labor, we searched the case reports according to the analysis by Seth et al [1,2,[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] as well as other cases indexed in Pubmed since 2002-2012 and tried to document its mode of diagnosis, complications and management during antenatal period and labor (Table 1). Though bladder stones are often found in women with urinary stasis due to outlet obstruction (pelvic organ prolapse, urethral stricture) and detrusal instability resulting in significant post-void residual urine, it is also found in healthy women [3].…”

Bladder Stone in Pregnancy: A Case Report and Review of the Literature

“…At time of delivery, obstruction of labor is the most common presentation of bladder stones, especially large bladder stones. They can interfere with descent of the fetal head [13–21]. Management of these cases has involved cesarean delivery with subsequent cystolithotomy at the time of cesarean or weeks later.…”
