“…The appearances of the upper urinary tract on sonography as observed in this study and on IVU as described previously 6,7 are not pathognomonic for obstetric fistulae as these appearances are well observed in other causes of lower urinary tract obstruction or infection. Therefore, in terms of the assessment of structural abnormalities, sonography is well suited, and the physiologic status of the kidneys could be assessed by the serum levels of electrolytes and urea.…”

“…Previously radiography either was unable to identify a definite fistulous track 7 as demonstrated by IVU in this study or was only able to show the fistula as a midline "opacity-within-an-opacity." 6 The exact location and size are infrequently seen in these conventional ways, but sonography has been able to demonstrate the course, site, and size of the fistula in about one third of the cases.…”

“…Although the literature has several reports on surgical management of such fistulae, [1][2][3]8 information about radiologic findings has been limited to that from plain films and excretory urograms. [4][5][6][7] Interestingly, the most common mode of evaluation of the female pelvis globally is by ultrasonography, but so far no report has analyzed the sonographic appearances in this condition.…”

Twenty‐two patients with 24 fistulae were examined prospectively with real‐time sonography. Sonographic findings were compared with those of intravenous urograms and correlated with the findings at examination under anesthesia and at surgery. Various genital abnormalities not revealed by intravenous urography were demonstrated by sonography preoperatively. These included cervical injuries, vesicovaginal fistula showing "flat tire" sign and hourglass deformities, and identification of the site, size, and course of fistulae in seven (29%) of the cases. However, the demonstration of the fistulae by sonography is poor relative to that of examination under anesthesia, in which 21 (87%) of the fistulae were identified. The factors responsible for the difficulty in demonstrating the fistulae on sonography, which included size and multiplicity, are discussed. Sonography is complementary to examination under anesthesia in preoperative evaluation of the patients with obstetric fistulae in general and in those with previous unsuccessful repairs in particular.

“…In patients with obstetric VVFs, other IVU abnormal- ities such as medial deviation of the pelvic ureters and pseudoprostatic bladder base indentation may be seen; there may also be bone changes, particularly osteophyte formation on the superior pubic ramus. 5 Computerized tomography may reveal contrast-opacified urine pooling within the vagina, but spatial and contrast resolution are too poor to permit visualization of the fistulous tract.…”

Worldwide, the most common cause of vesicovaginal fistula (VVF) is obstructed labor causing bladder ischemia, but in Western countries it occurs most often as a complication of gynecological surgery, especially abdominal hysterectomy.1 It may also occur as a complication of urological procedures—urethral dilatation, plastic bladder repair, and papilloma fulguration. Less common causes are trauma, sepsis, radiotherapy, and malignancy. It is a recorded complication of a large bladder calculus.2 We present a patient with carcinoma of the cervix in whom a VVF occurred immediately postradiotherapy. Ultrasound examination clearly demonstrated the position and size of the fistula.

“…[7] Akamaguna et al; found that stones were found only in 7% of VVF cases on radiological evaluation. [8] The presentation of VVS may vary from suprapubic pain,repeated urinary tract infections,pyuria,dysuria,,hematuria and urinary leakage. For diagnosis of VVS only pervaginal examination is required without need of any investigations.…”

Vesicovaginal fistula (VVF) due to various obstetric or gynecological causes is not uncommon but vesicovaginal stone in association with VVF is extremely rare presentation. The symptoms of vesicovaginal stone may be variable from recurrent urinary tract infections to perineal swelling with urinary incontinence. To diagnose stone associated with VVF only pervaginal examination is sufficient without need of any invasive investigations but still it is missed or diagnosed lately. To increase knowledge of this unusual condition we present case series of four such rare cases to outline safety and efficacy of endoscopic laser lithotripsy approach to manage vesicovaginal stone. We have used endoscopic laser lithotripsy method to clear the vesicovaginal stone which is minimally invasive way to provide early recovery by avoiding open surgical approach. Subsequently fistula can be repaired successfully after 6 weeks once bladder and vaginal wall infection and inflammation related to stone subside. To minimize morbidity in our cases we have specially used holmium laser energy to break the stone.
