A Caesarean section is the delivery of a baby through a surgical incision in the abdomen and uterus. Caesarean sections can be classified as either ‘elective’ (planned) or ‘emergency’. Emergency Caesarean sections can then be subclassified into three categories, based on their urgency. This is to ensure that babies are delivered in a timely manner in accordance to their or their mother’s needs. The Royal College of Obstetricians and Gynaecologists (RCOG) recommends that when a Category 1 section is called, the baby should be born within 30 minutes (although some units would expect 20 minutes). For Category 2 sections, there is not a universally accepted time, but usual audit standards are between 60-75 minutes. Emergency Caesarean sections are most commonly for failure to progress in labour or suspected/confirmed fetal compromise.

Percutaneous Nephrolithotomy (PCNL) Kidney stones are formed in the urinary tract due to the crystallization of chemical compounds in the urine. PCNL is a technique used to remove certain stones in the kidney or upper ureter (the tube that drains urine from the kidney to the bladder) that are too large for other forms of stone treatment such as shock wave lithotripsy or ureteroscopy. The Surgery This procedure has been performed on many patients over the last several years and is an accepted standard of care for patients with kidney stones that are large, very firm, or resistant to other forms of stone treatment. As such it has replaced open operations for kidney stones in the vast majority of patients. Typically, the length of the surgery is one to two hours. The surgery is performed by making a small 1 cm incision in the patient’s flank area. A tube is placed through the incision into the kidney under x-ray guidance with the help of a C-Arm. A small telescope is then passed through the tube in order to visualize the stone, break it up and remove it from the body. If necessary a laser or other device called a lithotripter may be used to break up the stone before it can be removed. This procedure has resulted in significantly less post-operative pain, shorter hospital stays, and an earlier return to work and daily activities when compared to open stone surgery. This technique also has a higher success rate for clearing all stones in one setting than other techniques such as extracorporeal shock wave lithotripsy (ESWL), which often require several attempts. Potential Risks and Complications Although this procedure has proven to be very safe, as in any surgical procedure there are risks and potential complications. The safety and complication rates are similar when compared to open surgery. Potential risks include: Bleeding Infection Tissue / Organ Injury Conversion to open surgery Failure to Remove the Stone
