Patients with chronic periodontitis are more likely to develop upper urinary tract stone: a nation-wide population-based eight-year follow up study.

ABSTRACT:

Background

The purpose of this study was to investigate the relationship between chronic periodontitis (CP) and upper urinary tract stone (UUTS) in Taiwan by using a population-based data set.

Methods

A total of 16,292 CP patients and 48,876 randomly-selected controls without chronic periodontitis were selected from the National research database and studied retrospectively. Subjects selected have not been diagnosed with UUTS previously. These subjects were prospectively followed for at least eight years. Cox regression models were used to explore the connection between risk factors and the development of UUTS.

Results

The CP patients have a greater chance of developing UUTS compared to controls (1761/16292, 10.8% vs. 4775/48876, 9.8%, p-values < 0.001). Conditioned logistic regression suggested CP increases the risk of UUTS development (HR 1.14, 95% CI [1.08-1.20], p < 0.001). After respective adjustment for age, gender, hypertension and diabetes, results showed that CP still increases the risk of developing UUTS (HR 1.14, 95% CI [1.08-1.20], p < 0.001).

Conclusion

By using a population-based database with a minimum eight 8 follow-up of CP in Taiwan, we discovered patients with CP are more likely to develop UUTS.

Project description:BackgroundTo evaluate the feasibility and effect of upper urinary tract videourodynamics in complex reconstructed upper urinary tract.MethodsFrom January 2016 to December 2018, patients who underwent complex upper urinary tract reconstruction and received upper urinary tract videourodynamics were included in the study. The modified Whitaker test was performed at 3 months after operation. The relative pelvic pressure was defined as the pelvic pressure minus the bladder pressure. Based on the flow rate, the test was divided into physiological phase and high flow phase. The results of pressure and image were classified into 3 types. Successful nephrostomy removal was defined as no symptoms and improved or stable hydronephrosis.ResultsA total of 12 patients who underwent complex upper urinary tract reconstruction received modified Whitaker test. All tests were successfully completed without adverse reactions. The relative pelvic pressure of 3 patients kept steady near the baseline throughout the examination and was classified into type 1. The pelvic pressure of 7 patients increased as the perfusion continued, and the relative pressure dropped to relative low level due to the peristalsis of ureter (type 2). The pressure of 2 patients increased along with increasing perfusion speed, and the relative pelvis pressure could easily reach 15 cmH2O. The peristalsis of ureter disappeared or appeared very weakly on the video record (type 3). Patients in type 1 (3 cases) and type 2 (7 cases) groups were allowed to remove the nephrostomy tube immediately. Patients in type 3 group needed to keep the nephrostomy for close follow up, and the tubes were removed 2 weeks and 4 weeks after the examination, respectively. None of the 12 patients received further treatment for recurrent symptoms and exacerbation of hydronephrosis.ConclusionsThe modified Whitaker test is initially safe and feasible in postoperative evaluation of complex upper urinary tract reconstruction surgery. Detailed results can provide more evidence to judge whether nephrostomy tube could be removed safely.
