Survey Safety01:28

Survey Safety

419
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Household Wiring And Electrical Safety01:13

Household Wiring And Electrical Safety

1.7K
Companies that supply power to most modern households use three conductors, typically called a three-wire line. While one is neutral, the other two are both at 120 V but with opposite polarity, giving a voltage of 240 V between them. With a three-wire line, high-power appliances that require 240 V, such as electric stoves and clothes dryers, are linked between the two hot lines. 120 V appliances can be connected between the neutral and either of the hot lines. The neutral side, which is always...

Buffer Effectiveness02:19

Buffer Effectiveness

55.6K
Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised.
The buffer capacity is the amount of acid or base that can be added to a given volume...

Framing Effects03:26

Framing Effects

8.0K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Biological Effects of Radiation02:59

Biological Effects of Radiation

18.1K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

Self-Awareness and Its Effects01:21

Self-Awareness and Its Effects

318
Self-awareness is a psychological state in which the individual becomes the focal point of their attention. This inward focus transforms the self into an object of contemplation and assessment, influencing how individuals perceive their actions and their alignment with personal and societal standards.Triggers and Contexts for Self-AwarenessSelf-awareness can be activated by external stimuli that make individuals visually or audibly aware of themselves, such as mirrors, cameras, or recordings.

Area of Science:

  • Urology
  • Nephrology
  • Surgical Procedures

Background:

  • Bilateral renal calculi present a complex treatment challenge.
  • Percutaneous nephrolithotomy (PCNL) is a standard treatment for kidney stones.
  • Simultaneous bilateral PCNL offers a potential solution for patients with stones in both kidneys.

Purpose of the Study:

  • To evaluate the effectiveness and safety of simultaneous bilateral percutaneous nephrolithotomy.
  • To assess stone-free rates, clinical success, and complication profiles.
  • To determine the feasibility of this approach in a prospective cohort.

Main Methods:

  • Prospective study (September 2012 - November 2016) including 18 patients with bilateral kidney stones.
  • Standard PCNL technique in prone position with fluoroscopic guidance and 24Ch tract dilation.
  • Data collected on demographics, stone characteristics, operative time, hospital stay, stone-free rate, complications, and follow-up.

Main Results:

  • 80% stone-free rate achieved.
  • Median stone burden was 228mm², operative time 150 minutes, and hospital stay 5 days.
  • Major complications included 4 cases of severe hemorrhage requiring embolization; 22.2% of renal units had residual calculi requiring further treatment.

Conclusions:

  • Simultaneous bilateral PCNL is an effective and safe treatment for bilateral renal calculi.
  • The procedure is a surgical challenge requiring careful patient selection.
  • Successful outcomes are achievable in experienced centers with appropriate patient selection and management.
