Blood urea and creatinine levels were 28<span class="elsevierStyleHsp" style=""></span>mg/dl and 2.0<span class="elsevierStyleHsp" style=""></span>mg/dl, respectively, and urine culture sensitivity was sterile. USG abdomen revealed normal sized right kidney and enlarged left kidney (14<span class="elsevierStyleHsp" style=""></span>cm) with dilated pelvic-calyceal system (3.2<span class="elsevierStyleHsp" style=""></span>cm) and thinned out renal parenchyma. Upper part of left ureter was also dilated and tortuous and final impression was left sided hydro-ureteronephrosis (HDUN). Intravenous urography and micturating cysto-urethrogram revealed HDUN with pelvic ureteric junction obstruction (PUJO) on the left side (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>a–g). Dynamic renal scintigraphy revealed normal functioning right kidney while a large photopenic area with gradual tracer collection without significant tracer clearance was noted on the left side (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>a–e), suggestive of PUJO. Patient underwent modified Anderson Hyne's pyeloplasty of left side with double J stenting.

To assess the response, a follow up renal dynamic scintigraphy was performed two months after surgery (performed in same manner as pre surgery) (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>f–j). It showed a normal functioning right kidney and mildly enlarged hydronephrotic left kidney showing moderately impaired function and delayed clearance. Compared to the previous study, a significant decrease in size of left kidney and improvement in function and drainage was observed. Additionally, lower poles of both kidneys appeared to be fused in midline giving appearance of a horseshoe kidney. To confirm this additional finding, patient was subjected to renal cortical scintigraphy with <span class="elsevierStyleSup">99m</span>Tc-DMSA and SPECT/CT.
