  Abstract 


Urinary stones are one of the most common complications of urinary diversions. We report the case of a 40-year-old man with renal and ureteric stones after radical cystectomy and ileal conduit. Normally renal stones are fragmented and removed through the ureters and urethra. However, in this patient with ileal conduit, the neo ureteric orifices being extremely narrow and because of the delicate wall of the ileum percutaneous nephrolithotomy has become the best option of treatment.

  Introduction Top


Radical cystectomy is the removal of the entire bladder, pelvic lymph nodes (lymphadenectomy), surrounding fat and fascia, lower ureters, prostate, prostatic urethra, and seminal vesicle that may contain cancer cells, done in patients with muscle-invasive carcinoma bladder. To make a new passage for urine, an ileal conduit which uses a portion of the distal ileum is made. This allows urine to pass from the kidneys through the conduit and out through an opening on the skin of the abdomen into an appliance attached to the anterior abdominal wall. These patients are at an increased risk of development of stones in the upper urinary tract, largely due to metabolic derangements and sepsis. Percutaneous nephrolithotomy (PCNL) is the standard of treatment for large stone burdens. Other methods include extracorporeal shockwave lithotripsy and antegrade or retrograde ureteroscopic lithotripsy.


  Case Report Top


A 48-year-old man was diagnosed with a case of carcinoma of the bladder, and he underwent transurethral resection of bladder tumor. Biopsy revealed it to be transitional cell carcinoma and inverted papilloma. He had progression of tumorn after 8 years and underwent radical cystectomy and urinary diversion.

Four years later, he had right flank pain and was diagnosed to have bilateral nephrolithiasis and bilateral ureteric calculi with right pyelonephritis and bilateral hydroureteronephrosis on ultrasound abdomen for which he was admitted. His serum creatinine level was 3.7, and bilateral percutaneous nephrostomy (PCN) under ultrasonography guidance was done. Once serum creatinine levels were normal, computed tomography urogram showed bulky right kidney with multiple calculi seen in the middle and lower calyx and the largest one at the level of the upper ureter (L3 level) measuring 20 mm × 8 mm along with right pyelonephritis. Left nephrolithiasis with left upper ureteric calculus measuring 9 mm along with mild hydronephrosis was seen [Figure 1] and [Figure 2].

He underwent bilateral PCNL, and complete stone clearance was achieved [Figure 3]. Intraoperatively few fragments went down the ureter for which 6/7.5 Fr rigid ureteroscope was used to retrieve fragments from upper ureter [Figure 4].

  Discussion Top


The urinary stone formation is one of the most common adverse events out of the myriad of complications in patients with urinary diversions.[1] These stones form in the upper urinary tract or in the diversion itself. The diversions that form a reservoir are more prone to develop stones within the pouch. The patients with an ileal conduit that only provides a passage but not a reservoir have upper urinary tract dilatation and urinary stasis contributing toward the urinary stone formation. Hyperchloremic metabolic acidosis because of increased reabsorption of solutes across intestinal mucosa is mainly responsible for calculus formation.[2]

After radical cystectomy and ileal conduit, this patient also presented with renal and upper ureteric stones along with hydronephrosis and right pyelonephritis. The advent of minimally invasive endoscopic techniques has reduced hospital stay and has hastened recovery postoperatively. These techniques include PCNL, extracorporeal shock wave lithotripsy (ESWL), antegrade or retrograde ureteroscopic lithotripsy.[3]

PCNL is the standard of care for renal stones, abnormal renal anatomy, and stones not amenable to ureteroscopy.[4] ESWL is a good treatment option in patients with urinary tract reconstruction because of difficulties in endoscopically accessing the ureter.[5] In patients with ileal conduit, neo ureteric orifices being narrow are difficult to visualize, and it is difficult to gain percutaneous renal access since contrast cannot be infused into the collecting system.

In this patient, with the combined guidance of ultrasound and fluoroscopy PCN was done and later, PCNL was done through the same tract for successful stone clearance.
