(a) A complete staghorn calculus of the left kidney (about 8 cm). (b) After the 1st ECIRS, a renal stone in the pelvis was removed. (c) After the 2nd ECIRS, most of the renal stone was removed. (d) After the last ECIRS, a stone-free state was achieved.

Renal pelvis carcinoma associated with staghorn calculus is a clinically rare condition. A 66-year-old man presented with flank pain due to an 8 cm complete staghorn calculus. We performed three lithotomies using endoscopic combined intrarenal surgery and carried out intraoperative biopsy. Histopathological examinations revealed a keratinized lesio...

Squamous Cell Carcinoma (SCC) of the kidney is a rare neoplasm usually associated with long-standing nephrolithiasis. This disease has a poor outcome as it is highly aggressive and presents at an advanced stage. In this case report, we offer the SCC of the kidney in a middle-aged man who underwent Percutaneous Nephrolithotomy (PCNL) for long-standing renal stones. After a few days, there were recurrent episodes of pyelonephritis. After proper evaluation, renal mass was detected, and the patient underwent a radical nephrectomy. SCC was diagnosed from histopathology, and systemic therapy was started, but the patient died. So, the possibility of this rare neoplasm should be considered while treating long-standing nephrolithiasis. Bangladesh J. Urol. 2022; 25(1): 62-66
Objectives
To report the clinical characteristics of patients who were incidentally diagnosed renal pelvic tumor during or after percutaneous nephrolithotomy (PNL).
Methods
The profiles of about 8,000 patients who underwent PNL in our center from 2011 to 2021 were retrospectively reviewed, six patients were diagnosed with renal pelvic tumor during or after PNL. Clinical data of these six patients were collected and summarized.
Results
Four males and two females with the average age of 59 years were researched. Chief complaints included loin pain, gross hematuria, and wound infection after PNL. Two patients had a definite long history of stones. Urinary tract infection occurred in 5 patients and all six patients had gross hematuria or microscopic hematuria. CT images revealed severe hydronephrosis in 4 patients and moderate hydronephrosis in 2 patients. Both staghorn and multiple stones were separately seen in 3 patients. Five patients were diagnosed with renal pelvic urothelial carcinoma via biopsy during PNL. One patient was diagnosed with renal pelvic tumor with extensive invasion by postoperative CT scan and received palliative treatment. Of two patients underwent radical surgery, one patient obtained long survival. One patient received endoscopic tumor resection and also obtained long survival. Two patients underwent renal artery embolization, one patient was still alive after 22 months, the other patient showed tumor growth in 3 weeks.
Conclusions
The possibility of renal pelvic tumor should be considered in stone patients with several risk factors including elder age, long history of stones, complicated stones, hydronephrosis especially pyonephrosis, obvious hematuria etc.
