Ureteral Stent Induced Urinary Tract Infection and Microbial Inconsistency Between Bladder and Renal Pelvis

Abstract The aim of this work was to determine which part of a double-J ureteral stent (DJ stents) showed the highest tendency to crystal, calculi, and biofilm deposition after ureterorenoscopic-lithotripsy procedure (URS-L) to treat calcium oxalate stones. Additionally, the mechanical strength and the stiffness of DJ stents were evaluated before and after exposure to urine. Obtained results indicated that the proximal (renal pelvis) and distal (urinary bladder) part is the most susceptible for post-URS-L fragments and urea salt deposition. Both, the outer and inner surfaces of the DJ ureteral stents were completely covered even after 7 days of implantation. Encrustation of DJ stents during a 31-day period results in reducing the Young’s modulus by 27–30%, which confirms the loss of DJ stent elasticity and increased probability of cracks or interruption. Performed analysis pointed to the need to use an antibacterial coating in the above-mentioned part of the ureteral stent to prolong its usage time and to prevent urinary tract infection.

Ureteral Stenting

Abstract Background Ureterosciatic hernia is a rare type of pelvic floor herniation that occurs through the sciatic foramen. The resulting ureteral obstruction may lead to hydronephrosis and to further complications including urinary tract infection and urosepsis. There have been 30 reported cases of ureterosciatic hernia. Ureteral stenting and surgical repair have been used as treatment options. Case presentation We report the case of an 86-year-old woman who was transferred to Tokyo Metropolitan Bokutoh Hospital with symptoms of fever and septic shock. Her computed tomography scan revealed left hydronephrosis and deviation of the left ureter into the sciatic foramen; she was therefore diagnosed with a left ureteral sciatic hernia and admitted in our intensive care unit for further treatment with resuscitative fluids, vasopressors, and antibiotics. Following a retrograde insertion ureteral catheter insertion, ureteral incarceration was relieved, and a double-J ureteral stent was placed in situ. Antibiotic treatment was initiated, and the patient’s hemodynamic status gradually improved. Conclusions Although ureterosciatic hernia is a rare disorder, it is associated with serious complications including urinary tract infection with sepsis, which may warrant urgent corrective procedure to relieve the structural obstruction. Treatment may be conservative or surgical, though treatment with ureteral stent placement may be a favorable approach in elderly patients with multiple comorbidities presenting with urosepsis.

Forgotten Ureteral Stent

Introduction Forgotten indwelling ureteral stents can cause significant urological complications. Only few cases are reported after kindney transplantation. Materials and Methods We present a case of a 39-year-old woman, transplanted in 1993 and referred to our Transplant Center 8 years later, because of a serious urinary tract infection with renal function impairment. Abdominal CT scan showed pyelonephritis and hydronephrosis in the transplanted kidney and the presence of a calcific ureteral stent, which had been forgotten in situ for 8 years. The stent was removed, but it was impossibile to replace it with a new stent both retrogradely and anterogradely, because of a tight obstruction of the mid ureter. So a uretero-ureteral anastomosis with up urinary tract was performed. Results No intra- or post-operative complications occurred. At 9 years’ follow-up, the patient shows an optimal renal function, with no urinary tract infection. Discussion A forgotten ureteral stent in a trasplanted kidney can cause a lot of complications and can lead to graft loss. The prosthesis may cause an irreversibile ureteral damage, so, as in our experience, forgetting a ureteral stent can result in a complex surgery.

We report a case of pseudotuberculous granulomatous pyelitis in an elderly female patient with hydronephrotic right kidney secondary to obstructing urinary stone. Pseudotuberculous granulomatous pyelitis is a rarely reported entity, characterized by severe granulomatous inflammation limited predominantly to the renal pelvis. It is associated with urinary (pelvicalyceal) obstruction, urolithiasis well as non- Mycobacterial urinary tract infection.

Bilateral Hydronephrosis

Abstract Vesicoureteral reflux is characterized by the retrograde flow of urine from the bladder to the kidneys. Vesicoureteral reflux may be associated with urinary tract infection, hydronephrosis, and abnormal kidney development (renal dysplasia). Hydronephrosis - literally “water inside the kidney” - refers to distension and dilatation of the renal pelvis and calyces, usually caused by obstruction of the free flow of urine from the kidney. Untreated, it leads to progressive atrophy of the kidney. In cases of hydroureteronephrosis, there is distention of both the ureter and the renal pelvis and ureteres. However, in the current era, hydronephrosis that is evident on fetal ultrasonography often heralds a ureteral abnormality. Hydronephrosis is defined as dilatation of the renal pelvis and/or calyces. Vesicoureteral reflux may present before birth as prenatal hydronephrosis, an abnormal widening of the ureter or with a urinary tract infection or acute pyelonephritis. The authors present a case of bilateral VUR of IVth grade associated with congenital hydronephrosis of IIIrd grade, diagnosed before birth with bilateral hydronephrosis, and taken into evidence at 2 months when he was first diagnosed with urinary tract infection. Positive diagnosis was facilitated by laboratory investigations (urine analysis, urine culture, voiding cystourethrography, static renal scintigraphy).
