Perioperative Tamsulosin for Treating Voiding Dysfunction Following Prostate Biopsy

The goal of this clinical trial is to learn if the drug Tamsulosin Hydrochloride works to treat urination difficulties after a prostate biopsy in men.The main questions it aims to answer are: * Does Tamsulosin Hydrochloride lower the rate of Acute Urinary Retention (inability to urinate) after a prostate biopsy? * Does Tamsulosin Hydrochloride improve participants' urination symptoms, quality of life, urine flow rate, and post-void residual urine volume? Researchers will compare the drug group to a control group (receiving no preventive medication) to see if Tamsulosin Hydrochloride works to prevent urination problems. Participants will: * Be randomly assigned to either take Tamsulosin Hydrochloride or receive no preventive medication. * If in the drug group, take one capsule of Tamsulosin Hydrochloride every night, starting 3 days before the biopsy and continuing until 6 days after the biopsy (10 doses total). * Undergo a standard prostate biopsy procedure (either through the rectum or perineum). * Return to the clinic 7 days after the biopsy for a follow-up checkup, which will include questions about their symptoms (IPSS and QoL scores) and tests to measure urine flow and bladder emptying.

Safety and Efficacy of MILEP Versus Standard EEP

Endoscopic enucleation of the prostate (EEP) is a standard treatment for benign prostatic hyperplasia (BPH), with modifications such as MiLEP that utilizes smaller instruments. The reduced resectoscope diameter in MiLEP may help decrease rates of stress urinary incontinence (SUI) and urethral strictures. Objective: to compare the efficacy and safety of MiLEP and standard EEP with a thulium fiber laser (TFL).

Proof-of-concept Study to Evaluate the Safety and Efficacy of Tryptophan in Patients with BPH.

Benign prostatic hyperplasia (BPH) is one of the most prevalent human diseases and a major cause of lower urinary tract symptoms (LUTS). Some men respond to current medical treatment (mainly α-1 adrenoreceptor antagonists and 5 α-reductase inhibitors), but a large proportion of patients continues to need a surgical procedure to treat resistant LUTS or even more serious complications of BPH, creating the emerging necessity for novel pharmacological therapies. Oxitriptan may have a possible positive effect on BPH associated symptoms with probably no impact in sexual function (which is a common side effect of the current drugs for BPH associated symptoms). Also, improvement in symptoms could be higher than that of current drugs used for this condition. This is a single-center parallel group, randomized clinical trial. The study will take place in Hospital de Braga (Urology department). Eligible patients will be randomized to receive tamsulosin 0.4mg (once a day, q.d.) or 5-HTP (5-hidroxitriptophan) 100mg (three times a day, t.i.d.), for 6 months.
