“…Although the published literature contains several small case reports of this phenomenon, to our knowledge, this is the first systematic review of renal forniceal rupture and its causes. In previously reported cases, ureteric calculi were the most identified causes of obstruction resulting in forniceal rupture [1–4], which is consistent with the findings of the present study. In our series, forniceal rupture was most commonly associated with distal ureteric calculi, with 75.7% of offending stones being located below the sacroiliac vessels.…”

“…Renal forniceal rupture is a radiographical finding indicating perirenal urinary extravasation associated with ureteric obstruction. The majority of reported cases involve ureteric calculi [1–4]. In addition, a small number of case reports have described other aetiologies, including malignant extrinsic ureteric compression [5–8], pregnancy [9,10], posterior urethral valves [11], pelvic‐ureteric junction (PUJ) obstruction [12], vascular extrinsic compression [13,14], iatrogenia [15,16] and i.v.…”

extrinsic ureteric compression in nine cases (8.3%), benign extrinsic ureteric compression in two cases (1.9%), pelvic-ureteric junction obstruction in two cases (1.9%), vesicoureteric junction (VUJ) obstruction in one case (0.9%), bladder outlet obstruction in one case (0.9%) and iatrogenic causes in four cases (3.7%).• No definitive cause was found in nine cases (8.3%). For patients in whom a ureteric stone was the cause of forniceal rupture, the level of obstruction was proximal ureter in 24.3% of cases, distal ureter in 17.6% of cases and VUJ in 58.1% of cases.• Mean ( SD ) stone size was 4.09 (2.0) mm. Mean ( SD ) stone size was 5.34 (1.87) mm for proximal stones, 4.08 (1.69) mm for distal stones and 3.53 (1.96) mm for VUJ stones ( P = 0.005).• Urinary tract infection was present in five out of 97 patients (5.2%) in whom data were available for analysis. CONCLUSION• The most common aetiology of renal forniceal rupture is obstruction caused by distal ureteric stones followed by malignant extrinsic ureteric compression.

Peripelvic extravasation associated with spontaneous rupture of renal pelvis is a rare occurrence, caused mostly by the obstruction due to calculus. However, the presence of renal anomalies increases the risk of rupture. Urinary extravasation leads to flank pain and may cause acute abdominal symptoms. Especially, the displacement of viscera by extravasated urine and the presence of gastrointestinal symptoms arising through intestinal reflex stimulation renders diagnosis more difficult. Ultrasonography, intravenous urography and computed tomography are the most efficient diagnostic tools in the diagnosis of pelvic renal rupture. In the present study, pre-and post-treatment radiological imaging findings of a case with renal pelvis rupture due to right ureter stone and the use of gray scale and color Doppler ultrasonography in the diagnosis has been discussed.

“…pyelogram is about 3% without any obstruction, while the risk increases from 5 to 33% when an obstruction is present) and also may be due to benign extrinsic compression of the ureter by a gravid uterus (it is rarely seen and is a significant complication in pregnancy). 13 In absence of such conditions, spontaneous rupture at any level of urinary collecting system is generally due to an obstruction of urinary tract by calculus, 12 with sudden increase of intraluminal pressure and this can cause rupture of its thin wall.…”
