Review
Fibroepithelial polyps (FEPs) are rare benign tumors of mesodermal origin. They are found in the ureters 85% of the time, with the remainder located in the renal pelvis and occasionally the bladder. FEPs can present as flank pain, lower abdominal pain, and/or gross hematuria. Previous literature reports management of these benign lesions using open surgical techniques, laparoscopic techniques, and endoscopic management. In this article, the authors present their pure endoscopic management of a large ureteral polyp and a review of the current literature outlining the etiology, clinical presentations, and management techniques for FEP of the ureter.

Ureteral fibroepithelial polyps are rare, accounting for approximately 2-6% of all ureteral tumors. They can be diagnosed by ultrasonography, computed tomography, and retrograde pyelography; however, diagnosis can be difficult. Management is by resection of the polyp, and endoscopic resection is the standard treatment. Partial ureteral resection and ureteral reconstruction may be necessary depending on the size and location of the polyp. Imaging follow-ups for approximately a year post-surgery are recommended. This clinical case report aimed to highlight a case of a fibroepithelial ureteral polyp that was managed by endoscopic resection.

Ureteral fibroepithelial polyps (UFP) are relatively rare, benign tumors. A total of 236 total cases were documented between 1932 and 2013. Notably, imaging studies, including computerized tomography (CT) and magnetic resonance imaging (MRI) are often negative. This report details a case of a patient with a UFP who presented with hematuria. CT suggested a possible 1.8 cm mass, but subsequent MRI was negative. Cystoscopy showed a polyp that prolapsed out of the left ureter and into the bladder with peristalsis. The patient subsequently underwent retrograde ureteroscopy and holmium laser excision of the polyp.

BACKGROUND
Ureteral fibroepithelial polyp is a rare benign lesion of the urinary tract. The incidence of the disease has been increasing recently; however, the aetiology of this tumour remains unclear. Early diagnosis and management are important, and endoscopic treatment is increasingly being preferred worldwide.
CASE DESCRIPTION
We report the case of a 49-year-old patient who presented with urinary frequency, intermittent haematuria, and an echogenic bladder mass found on pelvic sonography. Cystoscopy revealed an irregularly shaped large bladder mass, suggesting a benign or malignant bladder tumour. On subsequent examination, intravenous urography (IVU) and computed tomography showed a large lobulated contour filling defect in the bladder, measuring approximately 4 cm, with a suspected finding of a long stalk in the left distal ureter. Ureteroscopy revealed a long and narrow pedunculated tumour in the left distal ureter protruding into the bladder cavity through the ureteral orifice. On endoscopic excision, the attached stalk of the polyp into the ureter was cut using holmium:yttrium aluminium garnet (YAG) laser. The polyp was completely excised and extracted in its entirety, including the section protruding into the bladder. Histopathological findings confirmed the diagnosis of a fibroepithelial polyp. There was no sign of complication or recurrence on computed tomography performed after 12 months.
CONCLUSIONS
The ureteral fibroepithelial polyp protruding into the bladder mimicked a bladder tumour and was successfully treated by endoscopic resection, with no complications or recurrence. Endoscopic treatment is an effective and safe method to treat fibroepithelial polyps of the ureter.

Observational Study
To explore the expressions of calculus-related functional proteins in the ureteral calculus-adhered polyp tissues and investigate the role of these proteins in the formation of adhesions between the calculus and polyp.Patients with ureteral calculi and polyps who underwent ureteroscopic lithotripsy for the excision of polyps between January 2019 and June 2019 were enrolled. Polyps obtained from each patient were divided into 2 groups using a matched pairs design: observation group (polyps adhered to calculus) and control group (polyps not adhered to calculus). Histopathological examination of polyps was performed using hematoxylin and eosin staining. Polyp tissues were immunohistochemically stained to assess the expressions of calculus-related functional proteins, that is, annexin A1, calcium-binding protein S100A9 (S100A9), uromodulin, and osteopontin. Furthermore, quantitative analysis was performed using the H-score of tissue staining; Pearson correlation analysis was performed for proteins with high expression.Overall, 40 polyp specimens were collected from 20 patients with ureteral calculi combined with polyps (observation group, 20 specimens; control group, 20 specimens). Hematoxylin and eosin staining revealed obvious epithelial cell proliferation in polyps of both groups; crystals were observed in the epithelial cells of the polyp tissue in the observation group. The expression levels of annexin A1 and S100A9 in the observation group were significantly greater than those in the control group (P < .05). However, no obvious expression of osteopontin or uromodulin was observed in the polyp tissues of both groups. There was a strong correlation between the increased expressions of annexin A1 and S100A9 in the observation group (R = 0.741, P = .022).We documented increased expressions of annexin A1 and S100A9 in the ureteral calculus-adhered polyp tissues. Annexin A1 and S100A9 may play an essential role in the adhesion of calculus and polyp and the growth of calculi.

Primary ureteral fibroepithelial polyps (UFPs) are rare benign tumors of mesodermal origin. The majority UFPs are observed in the proximal part of the ureter and most commonly on the left side. The mean diameter of UFP is reported to be <5 cm. We herein present a rare case of a long primary ureteral polyp originating from the lower ureter in a 53-year-old woman. Following computed tomography, magnetic resonance imaging, retrograde pyelography and ureteroscopic examination, a preliminary diagnosis of giant primary lower ureteral polyp protruding into the bladder was obtained. Polyp resection and resection of the narrow ureteral segment with a V-shaped end-to-end anastomosis were performed. The length of this polyp was 15.0 cm, and the final pathological diagnosis was UFP. No recurrence or ureteral stenosis were observed at the 12-month follow-up. A supplementary review of previously published cases and related literature is also included.

Review
Robot-assisted laparoscopic (RAL) surgery is a safe, minimally invasive technique that has become more widely used in pediatric urology over recent decades. With several advantages over standard laparoscopy, robotic surgery is particularly well-suited to reconstructive surgery involving delicate structures like the ureter. A robotic approach provides excellent access to and visualization of the ureter at all levels. Common applications include upper ureteral reconstruction (e.g., pyeloplasty, ureteropelvic junction polypectomy, ureterocalicostomy, and high uretero-ureterostomy in duplex systems), mid-ureteral reconstruction (e.g., mid uretero-ureterostomy for stricture or polyp), and lower ureteral reconstruction (e.g., ureteral reimplantation and lower ureter-ureterostomy in duplex systems). Herein, we describe each of these robotic procedures in detail.

We present a unique case with a ureteral fibroepithelial tumor originating from the ureter, which could be confused with a bladder tumor on ultrasound examination due to its movement in and out of the bladder. METHODS: In cystoscopy, a papillary tumor lesion emerging from the right ureteral orifice was seen. After scanning the other quadrants, however, the tumor was not observed at the right ureteral orifice. It was then protruded back into the bladder. The tumor was seen several times to protrude into the bladder and return to the ureter, possibly due to ureteral peristalsis. Then, a semi-rigid ureteroscope was introduced through the right ureteric orifice, and the tumor was excised in one piece using Holmium laser fiber with 365μm of diameter. The size of the removed tumor was approximately 8 cm long. A double-j stent of 4.8 Fr was placed in the ureter. RESULTS: The patient was discharged on the first day without complications. The fibroepithelial polyps of the ureter, which consist of the stroma of mesoderm origin, covered with histologically normal or hyperplastic urothelial epithelial cells, are extremely rare tumors. It is important to distinguish these polyps from urothelial cancers, since these two entities are different in treatment and prognosis, although similar in symptoms and imaging procedures. CONCLUSIONS: Minimally invasive treatment techniques can be safely applied in the treatment of such exceedingly rare tumors.
