Prospective Randomized Controlled Trial to Evaluate the Effectiveness of Watching Movies to Decrease Anxiety During Extracorporeal Shock Wave Lithotripsy

Simultaneously combining a thulium fiber laser and holmium:YAG laser in vacuum-assisted mini-endoscopic combined intrarenal surgery on a complex renal calculus: A case report

Employing percutaneous nephrolithotomy to manage a complex renal calculus has always been challenging due to the blood transfusion requirement and the frequent necessity of using multiple access tracts. We report a novel treatment modality in the case of a 65-year-old male with a complex, large-volume renal calculus who was successfully treated by vacuum-assisted miniaturized endoscopic combined intrarenal surgery using the combination of a thulium fiber laser in retrograde fashion with a holmium:YAG laser in antegrade fashion. The kidney stone was entirely cleared, and the patient fully recovered with no adverse event.

Retrograde vacuum-assisted MiniPCNL system for large distal ureteric calculus removal: A case report

Large ureteral calculi are commonly associated with severe colic pain, complex urinary tract infections, severe hematuria, hydronephrosis, and renal deterioration, often requiring immediate surgical intervention. Ureteroscopy is a favored treatment due to its higher stone-free rates; however, it encounters difficulties in cases of a high burden of distal ureteral stones. We present a case where a patient with a significant ureteral calculus was effectively treated with a vacuum-assisted mini-percutaneous nephrolithotomy system in retrograde approach. This intervention enabled the complete removal of the stone, leading to the patient's full recovery without complications.

Prospective randomized controlled trial to evaluate effectiveness of virtual reality to decrease anxiety in office-based flexible cystoscopy patients

PURPOSE

To evaluate the effectiveness of immersive VR distraction technology in alleviating anxiety and pain during flexible cystoscopy.

METHODS

We prospectively recruited 270 study participants who qualified for flexible cystoscopy and randomly assigned them to experimental and control groups. The experimental group consisted of 135 patients who employed a VR set during flexible cystoscopy, and the control group consisted of 135 patients who underwent the procedure without a VR set. Patient anxiety was determined quantitatively according to the State-Trait Anxiety Inventory. A visual analog scale for assessing pain intensity, satisfaction, and willingness to repeat the procedure was evaluated. In addition, difference in the hemodynamic parameter was also examined.

RESULTS

The study findings demonstrated that the use of a VR set during flexible cystoscopy significantly improved the anxiety level over that of the control group (p = 0.001). Furthermore, this intervention led to a significantly increased level of satisfaction and willingness to repeat the procedure and a decrease in hemodynamic variables, specifically, systolic pressure, diastolic pressure, and heart rate (p = 0.001 in each case). Nonetheless, there were no significant differences between the groups with respect to the basic characteristic data, pain intensity, or oxygen saturation.

CONCLUSIONS

Based on the present study, immersive VR can measurably decrease anxiety and increase satisfaction and willingness to repeat the procedure during flexible cystoscopy.
