Background: Benign Prostatic Hyperplasia (BPH) manifests clinically by symptoms of the lower urinary tract. HPB symptoms rarely appear before age 40 but could have a prevalence of 16.6% in men over this age.

Objective: To determine the prevalence and degree of urinary symptoms in patients 40-45 years of age in the Family Medicine Unit #32.

Design and Setting: Descriptive cross-sectional study.

Methods: A descriptive cross-sectional study was conducted, using a non-probabilistic sampling for consecutive cases in a period of time from September to November 2019. The population was men under 45 years old who meet the inclusion criteria. The following variables were collected: age, diabetes mellitus, urinary symptoms, degree of urinary symptoms and quality of life. For statistical analysis, we applied descriptive statistics; for qualitative variables frequencies and percentages were used and for quantitative variables mean and standard deviation with the EPI-INFO version 7 software.

Results: Of the 228 participants, 163 had urinary symptoms; 157 (69%) with mild symptoms and 6 (3%) with moderate symptoms. In quality of life 82% (n=36) of patients were pleased with their current quality of life.

Conclusion: a high percentage of the population presented lower urinary tract symptoms, its evaluation and monitoring is important to prevent urinary diseases.

Benign prostatic hyperplasia (BPH) is currently the most common benign tumor in men [1]. It is a disease with high prevalence that affects 50% of men between 50 and 60 years [2] and more than 90% in men over 80 years [1]. BPH manifests clinically through Lower Urinary Tract Symptoms (LUTS) [2], these symptoms are important for diagnosis although are not exclusive to benign prostatic hyperplasia. LUTS include symptoms of filling, emptying and post-voiding, its most frequent manifestation is mixed although the filling symptoms are the most frequent (nocturnal polyuria and increased frequency in urination) [3]. The spontaneous evolution of BPH, without therapeutic intervention, tends to get worse but slowly and progressively; an early diagnosis is necessary to reduce the impact of the disease as well as its possible complications such as acute urine retention, prostate cancer or kidney failure [4].

One way to objectively measure this type of symptoms is through the International Prostate Symptom Score (IPSS) scale which describes its results as asymptomatic, mild symptomatology, moderate symptomatology and severe symptomatology [5]. Current policies indicate that the digital rectal examination should be performed for all patients with LUTS [6], the suspected diagnosis of benign prostatic hyperplasia based on physical examination and symptomatology has a positive predictive value (PPV) of 69.8% and increases to 77.1% with the prostate specific antigen (PSA). It is suggested to perform prostate antigen only in patients with LUTS suggestive of bladder obstruction secondary to benign prostate growth [6], since it has been shown that there is no statistically significant correlation between prostate volume variables and IPSS score [7].

The prevalence of Benign Prostatic Hyperplasia has increased due to population growth, increased life expectancy and changes in lifestyle [8]. It is a challenge for public health and the symptoms can be very pronounced and limit the patient's quality of life [9]. The use of simple and cheap tools allows the correct evaluation of prostate symptoms and allows to intervene earlier in this group of patients. Based on the above, the main objective of the study was to determine the prevalence, degree of urinary symptoms and quality of life in patients of 40-45 years in the Family Medicine Unit #32, Nuevo Leon, Mexico.


Study design and population

A descriptive cross-sectional study was conducted in Guadalupe, Nuevo Leon, Mexico, from September to November 2019. The research was carried out in the family medicine unit #32 (FMU 32) of the Instituto Mexicano del Seguro Social (IMSS); a primary care unit. Patients between 40-45 years of age were included. Patients with a history of urinary, renal or prostatic disorders were excluded and patients with incomplete information were eliminated.
