Transurethral resection of the prostate (also known as TURP, plural TURPs and as a transurethral prostatic resection TUPR) is a urological operation. It is used to treat benign prostatic hyperplasia (BPH). As the name indicates, it is performed by visualising the prostate through the urethra and removing tissue by electrocautery or sharp dissection. This is considered the most effective treatment for BPH. This procedure is done with spinal or general anesthetic. A large triple lumen catheter is inserted through the urethra to irrigate and drain the bladder after the surgical procedure is complete. Outcome is considered excellent for 80-90% of BPH patients. Because of bleeding risks associated with the surgery, TURP is not considered safe for many patients with cardiac problems. As with all invasive procedures, the patient should first discuss medications they are taking with their doctor, most especially blood thinners or anticoagulants, such as warfarin (Coumadin), or aspirin. These may need to be discontinued prior to surgery. Postop complications include bleeding (most common), clotting and hyponatremia (due to bladder irrigation).
Additionally, transurethral resection of the prostate is associated with low but important morbidity and mortality.
Uterine polyps, also called endometrial polyps, are usually small, bulb-shaped masses of endometrial tissue attached to the uterus by a stalk. They are soft, as opposed to uterine fibroids, which can grow much bigger and are made of hard muscle.
A breech birth is the birth of a baby from a breech presentation. In the breech presentation the baby enters the birth canal with the buttocks or feet first as opposed to the normal head first presentation.
There are either three or four main categories of breech births, depending upon the source:
* Frank breech - the baby's bottom comes first, and his or her legs are flexed at the hip and extended at the knees (with feet near the ears). 65-70% of breech babies are in the frank breech position.
* Complete breech - the baby's hips and knees are flexed so that the baby is sitting crosslegged, with feet beside the bottom.
* Footling breech - one or both feet come first, with the bottom at a higher position. This is rare at term but relatively common with premature fetuses.
* Kneeling breech - the baby is in a kneeling position, with one or both legs extended at the hips and flexed at the knees. This is extremely rare, and is excluded from many classifications.
As in labour with a baby in a normal head-down position, uterine contractions typically occur at regular intervals and gradually cause the cervix to become thinner and to open. In the more common breech presentations, the baby’s bottom (rather than feet or knees) is what is first to descend through the maternal pelvis and emerge from the vagina.
At the beginning of labour, the baby is generally in an oblique position, facing either the right or left side of the mother's back. As the baby's bottom is the same size in the term baby as the baby's head. Descent is thus as for the presenting fetal head and delay in descent is a cardinal sign of possible problems with the delivery of the head.
In order to begin the birth, internal rotation needs to occur. This happens when the mother's pelvic floor muscles cause the baby to turn so that it can be born with one hip directly in front of the other. At this point the baby is facing one of the mother's inner thighs. Then, the shoulders follow the same path as the hips did. At this time the baby usually turns to face the mother's back. Next occurs external rotation, which is when the shoulders emerge as the baby’s head enters the maternal pelvis. The combination of maternal muscle tone and uterine contractions cause the baby’s head to flex, chin to chest. Then the back of the baby's head emerges and finally the face.
Due to the increased pressure during labour and birth, it is normal for the baby's leading hip to be bruised and genitalia to be swollen. Babies who assumed the frank breech position in utero may continue to hold their legs in this position for some days after birth.

3:47 Risk of laparoscopy
Laparoscopy (from Ancient Greek λαπάρα (lapára) 'flank, side', and σκοπέω (skopéō) 'to see') is an operation performed in the abdomen or pelvis using small incisions (usually 0.5–1.5 cm) with the aid of a camera. The laparoscope aids diagnosis or therapeutic interventions with a few small cuts in the abdomen.[1]
Laparoscopic surgery, also called minimally invasive procedure, bandaid surgery, or keyhole surgery, is a modern surgical technique. There are a number of advantages to the patient with laparoscopic surgery versus an exploratory laparotomy. These include reduced pain due to smaller incisions, reduced hemorrhaging, and shorter recovery time. The key element is the use of a laparoscope, a long fiber optic cable system that allows viewing of the affected area by snaking the cable from a more distant, but more easily accessible location.
Laparoscopic surgery includes operations within the abdominal or pelvic cavities, whereas keyhole surgery performed on the thoracic or chest cavity is called thoracoscopic surgery. Specific surgical instruments used in laparoscopic surgery include obstetrical forceps, scissors, probes, dissectors, hooks, and retractors. Laparoscopic and thoracoscopic surgery belong to the broader field of endoscopy. The first laparoscopic procedure was performed by German surgeon Georg Kelling in 1901. There are two types of laparoscope:[2]
A telescopic rod lens system, usually connected to a video camera (single-chip or three-chip)
A digital laparoscope where a miniature digital video camera is placed at the end of the laparoscope, eliminating the rod lens system
The mechanism mentioned in the second type is mainly used to improve the image quality of flexible endoscopes, replacing conventional fiberscopes. Nevertheless, laparoscopes are rigid endoscopes. Rigidity is required in clinical practice. The rod-lens-based laparoscopes dominate overwhelmingly in practice, due to their fine optical resolution (50 µm typically, dependent on the aperture size used in the objective lens), and the image quality can be better than that of the digital camera if necessary. The second type of laparoscope is very rare in the laparoscope market and in hospitals.[citation needed]
Also attached is a fiber optic cable system connected to a "cold" light source (halogen or xenon) to illuminate the operative field, which is inserted through a 5 mm or 10 mm cannula or trocar. The abdomen is usually insufflated with carbon dioxide gas. This elevates the abdominal wall above the internal organs to create a working and viewing space. CO2 is used because it is common to the human body and can be absorbed by tissue and removed by the respiratory system. It is also non-flammable, which is important because electrosurgical devices are commonly used in laparoscopic procedures.[3]
Procedures
Surgeons perform laparoscopic stomach surgery.
Patient position
During the laparoscopic procedure, the position of the patient is either in Trendelenburg position or in reverse Trendelenburg. These positions have an effect on cardiopulmonary function. In Trendelenburg's position, there is an increased preload due to an increase in the venous return from lower extremities. This position results in cephalic shifting of the viscera, which accentuates the pressure on the diaphragm. In the case of reverse Trendelenburg position, pulmonary function tends to improve as there is a caudal shifting of viscera, which improves tidal volume by a decrease in the pressure on the diaphragm. This position also decreases the preload on the heart and causes a decrease in the venous return leading to hypotension. The pooling of blood in the lower extremities increases the stasis and predisposes the patient to develop deep vein thrombosis (DVT).[4]
Gallbladder
Rather than a minimum 20 cm incision as in traditional (open) cholecystectomy, four incisions of 0.5–1.0 cm, or more recently, a single incision of 1.5–2.0 cm,[5] will be sufficient to perform a laparoscopic removal of a gallbladder. Since the gallbladder is similar to a small balloon that stores and releases bile, it can usually be removed from the abdomen by suctioning out the bile and then removing the deflated gallbladder through the 1 cm incision at the patient's navel. The length of postoperative stay in the hospital is minimal, and same-day discharges are possible in cases of early morning procedures.[citation needed]
Colon and kidney
Colorectal surgeon Conor Delaney, MD, explains laparoscopic surgery for colon cancer, including how it works and what patients can typically expect before, during, and after the procedure.

With ECT, electrodes are placed on the patient's scalp and a finely controlled electric current is applied while the patient is under general anesthesia. The current causes a brief seizure in the brain. ECT is one of the fastest ways to relieve symptoms in severely depressed or suicidal patients.
