double-j (dj) stents are the main tools used in urological practice for prevention and treatment of obstruction. stenting is also mandatory after complicated ureteroscopy or tul (transureteral lithotripsy). known complications are upper migration of dj stents into the kidney and lower migration to the bladder. in a man with an impacted right lower ureteral stone, a dj stent was placed because t...
PURPOSE Double-pigtail ureteral stent is placed cystoscopically after ureteroscopy. We describe a technique for fluoroscopic placement of ureteral stents and demonstrate its use in a non-randomized prospective study. MATERIALS AND METHODS Double-pigtail stents were placed either fluoroscopically or cystoscopically in 121 consecutive patients. In the fluoroscopic method, the stent was placed o...
Purpose To evaluate urination-related quality of life (QoL) in patients with an indwelling ureteral stent immediately after ureteroscopic lithotripsy (URSL) for upper urinary calculi. We compared the effects of loop-tail and pigtail ureteral stents on urination-related QoL. Materials and Methods Of 135 patients who underwent URSL between May 2014 and March 2015 at our hospital, we retrospecti...
A 29-year-old woman with mild back pain when coughing and suprapubic discomfort after voiding was admitted to Pusan National University Hospital. Two weeks earlier, she had undergone a hysterectomy and right-sided ureteroneocystostomy for uterine atony and right ureteral injury with bladder rupture. Computed tomography showed that a ureteral J stent extended from the right ovarian vein to the r...
PURPOSE We assessed the near term comfort of newly designed ureteral study stents or marketed control stents, including Polaris and Percuflex stents. Study stents had distal 6Fr pigtail ends with 3Fr or less loops. Decreased material in situ was hypothesized to enhance comfort. Usefulness of the patient self-administered Ureteral Stent Symptoms Questionnaire (Stone Management Unit, Southmead Ho...
A prospective study of 30 renal units in 27 patients with double pigtail ureteral stents seen at our hospital was done. The aim of the study was to confirm or rule out the occurrence of vesicoureteral reflux radiologically, and to define its degree in stented patients. During the filling phase of the cystourethrogram, reflux occurred in 19 of the 30 renal units (63%). Of those 19 renal units th...
We report on the case of a 44-yr-old white man who was referred as an emergency from a local hospital to the medical intensive care unit (ICU) at our institution for progressive multiorgan failure of unknown cause. The CT scan of the abdomen showed a horseshoe kidney with extensive stone formation in both kidneys and the urinary bladder. A massively calcified double pigtail ureteral stent could...
BACKGROUND Circumcaval ureters (CU) are a rare embryological malformation resulting in ventral displacement of the caudal vena cava, which crosses the ureter, potentially causing a ureteral stricture. OBJECTIVES To evaluate cats with obstructed CU(s) and report the presenting signs, diagnostics, treatment(s), and outcomes. Cats with obstructed CU(s) were compared to ureterally obstructed cats...
Ureterosciatic herniation, the protrusion of the hernia sac through the sciatic foramen, is an extremely rare cause of ureteral obstruction. We describe a case revealed by severe left back pain in a 72-year-old female. She was referred to our hospital for urological assessment of left hydronephrosis observed by ultrasonography. Intravenous ureterography (IVU) showed findings compatible with a l...
There are four types of ureteral metal stents: self expandable, balloon expandable, covered, and thermoexpandable shape-memory. Insertion of metal stents requires expertise with transurethral and percutaneous techniques. The stricture is traversed with the aid of a guidewire via a percutaneous nephrostomy, and the stenotic segment is dilated using a high-pressure balloon catheter. The stent is ...
