Eggshell calcification of the urinary bladder in chronic
Article in Radiology case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Chronic urinary schistosomiasis is an important cause of hematuria and genitourinary morbidity in individuals from endemic regions. In advanced disease, computed tomography (CT) may show circumferential calcification of the bladder and distal ureters, a classic pattern that can suggest the diagnosis even when laboratory tests are negative. A 38-year-old man from Mozambique, living in Portugal with human immunodeficiency virus and hepatitis B virus infections, presented with 2 months of painless gross hematuria. He denied dysuria, fever, flank pain, weight loss, prior urinary tract instrumentation, tuberculosis, or recent travel, and baseline blood tests and renal function were normal. Urinalysis showed hematuria and leukocyturia, but multiple urine examinations for Schistosoma ova and a urine Schistosoma-specific polymerase chain reaction were negative. Noncontrast CT of the abdomen and pelvis was obtained and demonstrated diffuse circumferential calcification of the urinary bladder wall with distal ureteral involvement, producing a classic "eggshell" appearance without hydronephrosis, renal stones, or intraluminal mass. Cystoscopy showed yellowish plaques and nodular mucosal lesions, and targeted bladder biopsies revealed numerous calcified Schistosoma haematobium ova within the urothelium and submucosa with chronic inflammation and stromal calcification, confirming chronic inactive infection. The patient received a single dose of praziquantel 40 mg/kg and 3 months later, hematuria had resolved and renal function was stable. This case highlights that in chronic urinary schistosomiasis, CT findings can be decisive when urine-based tests are negative.
