Simple Renal Cyst Prevalence in Internal Medicine Department and Concomitant Diseases

Abstract

A total of 684 patients who had not been diagnosed with renal cyst but had undergone abdominal ultrasonography for various reasons were evaluated. Patients with and without renal cyst were classified into two groups and were compared in terms of hypertension (HT), hyperlipidemia (HL), diabetes mellitus (DM) and obesity (body mass index: > or = 30 kg/m2) prevalence. Although 94 patients (13.7%) were established with a renal cyst, 590 patients (86.3%) did not have a renal cyst. The mean age of the patients established with a simple renal cyst was 67.3 +/- 12.1 years (range: 28-82 years); 54 (57.4%) of them were women and 40 (42.6%) were men. Of the patients established with a simple renal cyst, 64 (68.1%) had HT, 40 (42.6%) had DM, 20 (21.3%) had HL, 42 (44.7%) were obese, 18 (19.1%) had nephrolithiasis, and 6 (6.4%) had urinary tract infection. Of the patients without a cyst, 272 (46.1%) had DM, 212 (35.9%) had HT, 122 (20.7%) had HL, and 96 (16.3%) were obese. HT and obesity were significantly higher in patients with a renal cyst when compared with those without a cyst. However, although HL incidence was higher in patients with a cyst, the difference was not significant statistically. HT, HL, and obesity are more prevalent in patients with a renal cyst when compared with patients without. Consequently, patients with a simple renal cyst should be evaluated and followed up in terms of atherosclerotic risk factors.

Association between simple renal cysts and development of hypertension in healthy middle-aged men

“…Our study extends the findings of a relationship between simple renal cysts and hypertension shown in previous cross-sectional and casecontrol studies [7,8,15].…”

Incidental Finding of Renal Masses at Unenhanced CT: Prevalence and Analysis of Features for Guiding Management

“…Subcentimeter masses were not considered in our analysis because incidental masses smaller than 1 cm can generally be ignored [10,17]. The prevalence in our study was similar to that in previous reports, particularly when subcentimeter masses were excluded [6,18].…”

Hyperuricemia and overexcretion of uric acid increase the risk of simple renal cysts in type 2 diabetes

“…Two case-control studies found no significant differences between SRC patients and controls 4, 18 . Cross-sectional studies on healthy subjects and internal medicine outpatients indicated that serum uric acid level were associated with SRC development upon univariate analysis 14, 15 , and, indeed, even upon multivariate analysis adjusted for confounders including age, sex, eGFR, and renal stones 17 . Blijderveen et al .…”

“…Some authors found that diabetes was not significantly associated with SRC development 8, 14, 18 . Others reported significant increases in the prevalence of diabetes (9.7–24.1%) in patients with SRC, but this was not significant upon multivariate modeling 1, 12, 15, 19 .…”

“…SRC have also been suggested to be associated with hypertension 7, 8 ; blood pressure normalization was reported after adequate treatment of SRC 9 . In general populations, all of poor renal function, hypertension, age 1, 10 , male gender 1, 10–13 , obesity 14, 15 , smoking 13 , renal stones 12, 13 and serum uric acid level 16, 17 are associated with SRC. It is important to identify (and eliminate) risk factors for SRC development.…”
