Evaluating temperature dynamics: a single-center prospective randomized pilot study of holmium versus thulium laser fiber for renal stones.

Background: We aimed to evaluate and compare the rise in the temperature for the safety of the kidney parenchyma on firing the Holmium: Yttrium Aluminium Garnet laser and the Thulium Fiber Laser during laser lithotripsy in humans.

Method: We included 30 pre-stented patients with renal calculi undergoing Retrograde intra-renal surgery. They were randomized into two groups - 15 patients underwent holmium laser lithotripsy and 15 patients underwent TFL laser lithotripsy.

Comparison of Temperature Changes Between Holmium-YAG Laser and Thulium Fiber Laser in an In Vitro Setting.

Objective: We aimed to evaluate and compare the rise in the temperature for the safety of the ureter and kidney parenchyma when firing the holmium laser and the thulium fiber laser (TFL).

Methods: We performed a laboratory experiment to measure the rise in temperature upon firing holmium laser and a TFL in a 10 cm3 transparent test tube in an outdoor environment and then in a container with normal saline.

Results: In a 10 cc test tube with static water at 25°C, the rise in temperature with holmium and TFL depends on the firing time, keeping power constant.

A comparison study of 68gallium-prostate-specific membrane antigen positron emission tomography-computed tomography and multiparametric magnetic resonance imaging for locoregional staging of prostate cancer.

Purpose: Prostate cancer (PCa) is the most common malignancy in men aged 50 years and older and the second cause of cancer death among men. Accurate staging of PCa preoperatively is of high importance for treatment decisions and patient management. Conventional imaging modalities (ultrasound, computed tomography [CT], and magnetic resonance imaging) are inaccurate for the staging of PCa.

Renal artery thrombosis and mucormycosis in a COVID-19 patient.

The novel coronavirus disease 2019 (COVID-19) has been postulated to be associated with hypercoagulability, leading to thromboembolism in major blood vessels. There are also increasing reports of invasive fungal infections in COVID-19 patients. We report a unique case of mucormycosis associated with renal artery thrombosis leading to renal infarction and nephrectomy in a COVID-19 patient.

Microsurgical Denervation of Spermatic Cord for Chronic Idiopathic Orchialgia: Long-Term Results from an Institutional Experience.

Purpose: Chronic testicular pain remains an important challenge for urologists. At present there are many treatment modalities available for chronic orchialgia. Some patients remain in pain despite a conservative treatment.

Low dose lignocaine + butorphanol vs. low dose bupivacaine for spinal anaesthesia in day care urological surgeries: a prospective randomized control trial.

Objective: A local anaesthetic with fast onset, short and reliable duration of anaesthesia may be preferable for day care urological surgeries. Low dose lignocaine is believed to act faster and to have a shorter duration of action than low dose bupivacaine. Use of lignocaine for spinal anesthesia is discouraged now a days because of rare reports of transient neurological symptoms.

Reprocessing and reuse of urological armamentarium: How correct are we!

Healthcare is expensive for a large proportion of the population in spite of high per capita income and good health insurance penetration. In an effort to reduce cost of the procedure, reprocessing of devices was started in the late 1970s. Reprocessing practice includes various measures such as proper cleaning, disinfection, and sterilization procedures.

Video endoscopic inguinal lymphadenectomy for radical management of inguinal nodes in patients with penile squamous cell carcinoma.

Background: Inguinal lymph node involvement is an important prognostic factor in penile cancer. Inguinal lymph node dissection allows staging and treatment of inguinal nodal disease. However, it causes morbidity and is associated with complications such as lymphocele, skin loss, and infection.
