Abstract

Introduction:

Successful outcomes have been reported for the treatment of lower urinary tract symptoms (LUTS) with the prostatic urethral lift (PUL) in a number of clinical investigations. Our aim was to investigate PUL outcomes in patients treated in a day-to-day clinical setting without the rigid exclusion criteria of clinical studies.

Materials And Methods:

We investigated the outcome of the PUL procedure at five German departments during the initial period when PUL was approved for the clinic (10/2012-06/2014). All candidates for transurethral resection of the prostate (TURP) received PUL information and were given the choice of procedures. The only exclusion criterion was an obstructive median lobe. No patients were excluded because of high post-void residual volume (PVR), prostate size, retention history or LUTS oral therapy. Maximum urinary flow (Qmax), PVR, International Prostate Symptom Score (IPSS) and Quality of Life (QOL) were assessed at baseline, 1, 6, 12, and 24 months after surgery.

Results:

Of 212 TURP candidates, 86 choose PUL. A mean of 3.8 (2-7) UroLift implants were implanted in patients of 38-85 years with a prostate size of 17-111 ml over 57 (42-90) min under general or local anesthesia. Thirty-eight (38.4%) patients had severe BPH obstruction and would have been denied PUL utilizing previously reported study criteria. Within 1 month 74 (86%) reported substantial symptom relief with significant improvements in Qmax, PVR, IPSS, and QOL (p < 0.001) that was maintained within the follow-up. Sexual function including ejaculation was unchanged or improved. No Clavien-Dindo Grad ≥ 2 was reported postoperatively. Eleven (12.8%) patients were retreated over 2 years. Twelve (86%) of 14 patients presenting with chronic urinary retention were catheter free at last follow-up.

Conclusion:

PUL is a promising surgical technique that may alleviate LUTS, even in patients with severe obstruction.

Lift

Lift

Lift is a fundamental aerodynamic force that acts perpendicular to the direction of airflow. It plays a central role in achieving and sustaining flight and in stabilizing various vehicles. Lift primarily originates from pressure differences created across surfaces, such as an airfoil. A lower pressure region forms above the wing, while a higher pressure region forms below it, generating an upward force. This differential results from the shape and orientation of the airfoil, enabling the wing...

Self-Efficacy

Self-Efficacy

Self-efficacy is the belief in one's capacity to organize and execute actions necessary to manage prospective situations. This belief significantly influences how individuals approach goals, tasks, and challenges across different domains of life.Psychological and Educational ImpactsIndividuals with strong self-efficacy are more resilient in the face of difficulties. They are more likely to adopt effective problem-solving strategies, persist through obstacles, and regulate emotions such as...

meta-Directing Deactivators: –NO2, –CN, –CHO, –&NoBreak;CO2R, –COR, –CO2H

meta-Directing Deactivators: –NO₂, –CN, –CHO, –⁠CO₂R, –COR, –CO₂H

All meta-directing substituents are deactivating groups. These substituents withdraw electrons from the aromatic ring, making the ring less reactive toward electrophilic substitution. For example, the nitration of nitrobenzene is 100,000 times slower than that of benzene because of the deactivating effect of the nitro group. The first step in an electrophilic aromatic substitution is the addition of an electrophile to form a resonance-stabilized carbocation. The energy diagrams for...

Types of Errors: Detection and Minimization

Types of Errors: Detection and Minimization

Error is the deviation of the obtained result from the true, expected value or the estimated central value. Errors are expressed in absolute or relative terms.
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
Systematic or...

2° Amines to N-Nitrosamines: Reaction with NaNO2

2° Amines to N-Nitrosamines: Reaction with NaNO₂

Secondary amines react with nitrous acid to form N-nitrosamines, as depicted in Figure 1. Nitrous acid, a weak and unstable acid, is formed in situ from an aqueous solution of sodium nitrite and strong acids, such as hydrochloric acid or sulfuric acid, in cold conditions. In the presence of an acid, the nitrous acid gets protonated. The subsequent loss of water results in the formation of the electrophile known as nitrosonium ion.

Dose-Response Relationship: Potency and Efficacy

Dose-Response Relationship: Potency and Efficacy

The potency of a drug is the measure of its ability to produce a biological response and can be compared by looking at the half-maximum effective concentration or EC50 values of different drugs. A lower EC50 value indicates higher potency of the drug. In the dose–response curve of two antihypertensive drugs, candesartan and irbesartan, a significant difference is observed in their EC50 values. A lower EC50 value for candesartan indicates that it is more potent than irbesartan, as it...
