This study compares two surgical methods for removing large staghorn kidney stones: flexible ureteroscopy (FURS) and percutaneous nephrolithotomy (PCNL). PCNL is the standard but can cause serious complications; FURS is less invasive but may need multiple sessions. The trial will…

This study compares two positions—lying on your back (lithotomy) versus lying on your side (lateral)—during a minimally invasive surgery for kidney stones smaller than 2 cm. The goal is to see which position helps clear stones more completely. Seventy adults with lower calyx kidn…

This study tests whether combining an antibiotic (linezolid) with a mucus-dissolving agent can reduce the sticky bacterial film (biofilm) that forms on ureteral stents placed after kidney stone surgery. About 100 adults who are stone-free and have a stent for one month will be ra…

This study looks at whether measuring oxygen levels in a central vein can help doctors decide if a patient with septic shock needs more fluids. About 115 adults with septic shock will have their oxygen levels checked before and after a fluid challenge. The results will be compare…

This study will test whether adding two different doses of dexmedetomidine to the standard epidural drug bupivacaine can provide effective labor pain relief while using less bupivacaine. Researchers plan to enroll 140 women in early labor. The goal is to see if this approach redu…

This study compares three types of nerve blocks used for pain relief during shoulder surgery. The goal is to see which block is least likely to temporarily paralyze the diaphragm, the main muscle used for breathing. Seventy-five adults having shoulder surgery will be randomly ass…

This study will compare deep versus moderate muscle relaxation during open hysterectomy in 88 women. Researchers want to see if deeper relaxation reduces pain, the need for opioid painkillers, and inflammation after surgery. The goal is to find the best approach to improve recove…

This study looks at how the size of the connector piece (abutment) on a dental implant affects the bone around it. Researchers will place implants in 40 adults with a missing back tooth and use either a narrow or regular abutment. Over 24 months, they will measure bone changes on…
