The safety and efficacy of MPR-CTU combined with precise intraoperative ultrasonography guided flexible ureteroscope in the treatment of renal cystic disease

Abstract

The safety and efficacy of multi-planar reconstruction (MPR) image post-processing technique-computed tomography (CT) urography (CTU) combined with precise intraoperative ultrasonography guided flexible ureteroscope in renal cyst incision and drainage in the treatment of cystic diseases of kidney were evaluated. A total of 68 patients were randomly divided into control and observation group (n=34). All the patients were treated with renal cyst incision and drainage under flexible ureteroscope. The control group was under ultrasound guidance. The observation group was combined with MPR-CTU, the safety and efficacy was compared. There was no significant difference between the two groups in the success rate and the time of cyst treatment (P>0.05). The incidence of intraoperative and postoperative complications of the observation group was significantly lower than that of the control group. After 1 month follow-up, the total effective rate of the observation group was significantly higher than that of the control group, the difference was statistically significant (P<0.05). Conclusion MPR-CTU technique combined with intraoperative ultrasonography to guide cyst incision and drainage under flexible ureteroscope for renal cystic disease has a high safety and efficacy, and it is worthy of clinical application.

Ultrasonography‑assisted flexible ureteroscope for the treatment of parapelvic renal cysts: A comparison between the 1470‑nm diode laser and the holmium laser

“…A recent Chinese randomized controlled trial confirmed that the injection of methylene blue into the parapelvic renal cysts reduced the identification time and operation time of the cysts under a flexible ureteroscope (21). A previous study revealed that MPR-CTU combined with a precise intraoperative ultrasonography-guided flexible ureteroscope exerted better therapeutic effects (increased the successful rate of surgery and reduced complications) via easily locating the cystic wall compared with the flexible ureteroscope technique (5).…”

“…Holmium lasers are commonly used for the incision and drainage of parapelvic renal cysts under a flexible ureteroscope (5,14,22). Yu et al (14) used a holmium laser to incise and drain endogenous symptomatic renal cystic diseases under a flexible ureteroscope.…”

“…The percutaneous approach is a safe and effective method for treating peripherally located simple renal cysts but carries a risk of damage to renal hilar structures and the collecting system for parapelvic cysts (2). With the development of technology, the advantages of flexible ureteroscopy have become more apparent in the treatment of parapelvic cysts (4,5). Parapelvic cysts are characterized by their complexity and proximity to the renal hilar structures (2,6).…”

Observations on the Curative Effect of a Holmium Laser Under a Flexible Ureteroscope in the Treatment of Endogenous Renal Cysts Combined with Renal Calculi

“…Laparoscopic renal cyst removal and decompression have advantages for abducted renal cysts, but for endogenous renal cysts, the operation is di cult, the window range is small, the trauma is large, and the operation time is long. In recent years, with the development of ureteroscopy technology, exible ureteroscopy combined with holmium laser surgery has advantages for the treatment of endogenous renal cysts and is widely used in clinical practice [4]. However, patients with renal cysts and kidney stones are rare.…”
