“…The spectrum of gongenital disorders includes focal and multifocal abnormalities leading to multicystic dysplastic kidney (MCDK), infundibulopelvic stenosis, calyceal diverticula, and ureteropelvic junction obstruction [8,9]. The theory assumes that infundibulopelvic dysgenesis is the result of early or late budding of the ureter during embryogenesis [10]. During normal development of the metanephros, glial cell line-derived neurotrophic factor (GDNF), a peptide secreted by the metanephric mesenchyme, stimulates and localizes outgrowth of the ureteric bud via activation of the RET receptor.…”

Urolithiasis is a common condition, and it represents a large number of hospital visits. Under the term infundibulopelvic dysgenesis, many conditions amongst a spectrum of congenital disorders of the pelvicalyceal system are described. Retrograde intrarenal surgery (RIRS) is an effective and safe treatment modality in the management of urinary system stone disease. Fluoroscopic imaging is a cornerstone in endourology. Herein, we present a case where we diagnosed an obstructed calyx during RIRS for renal calculi and operated on it. In this extraordinary case, contrast agent was trapped in the calyx mimicking a renal stone and that was the reason that we discovered the infundibular stenosis. The patient, 24 h after the operation, left the hospital without any complications reported.

Infundibulopelvic dysgenesis is a rare condition characterized by congenital malformation of the pelvicalyceal system. We present the case of an 18-year-old boy with chronic intermittent right flank pain and cystic dilation with parenchymal thinning on ultrasonography. The left kidney was normal. The patient denied dysuria, constipation, and history of UTIs or renal calculi. Cystoscopy with retrograde pyelogram showed marked stenosis of the right pelvicalyceal system and anatomy unfavorable to stenting. The patient's symptoms were unresponsive to conservative management. Reconstruction of the right collecting system was unsuccessful and a simple nephrectomy was performed, which led to complete resolution of his symptoms.
