Background: Cushing syndrome increases morbidity and mortality, which is mainly caused by cardiovascular disorders. This study reports the cardiovascular risk outcomes at 3, 6, and 12 months after unilateral laparoscopic adrenalectomy in cortisol-secreting adrenal tumor and to identify the preoperative parameters predicting the resolution of cardiovascular risk factors after surgery.

Methods: All clinical data of patients with unilateral cortisol-secreting adrenal tumors who underwent laparoscopic adrenalectomy in King Chulalongkorn Memorial Hospital between 2001-2022 were retrospectively reviewed.

Twice daily TAC (BID TAC) and prolonged released once daily dose tacrolimus (OD TAC) have different pharmacokinetic (PK) profiles in kidney transplant (KT) recipients. Precise dose adjustment recommendations when converting from BID TAC to OD TAC remain inconclusive. A single center, PK study was conducted in stable KT recipients taking constant doses of TAC, mycophenolic acid, and prednisolone.

Background: The role of laparoscopic adrenalectomy (LA) in a large adrenal tumor is controversial due to the risk of malignancy and technical difficulty. In this study, we compared the perioperative outcomes and complications of LA on large (≥ 6 cm) and (< 6 cm) adrenal tumors.

Methods: We retrospectively reviewed all clinical data of patients who underwent unilateral transperitoneal LA in our institution between April 2000 and June 2019.

Background: Tacrolimus is mainly metabolized by cytochrome P450 3A5 (CYP3A5), which is expressed in the liver. However, CYP3A5 is also expressed in the kidney tissue and may contribute to local tacrolimus clearance in the kidney allograft. We aimed to evaluate the association between the allograft CYP3A5 genotype and transplant outcomes.

Background: Intraabdominal carbon dioxide following laparoscopic adrenalectomy results in postoperative shoulder tip pain. Several interventions to reduce this pain have been used, but were not so effective.

Objective: To evaluate the efficacy of soft silicone drain in reducing shoulder tip pain after laparoscopic adrenalectomy.

We report a case of bladder alveolar soft part sarcoma in an 18-year-old Thai male patient who had been treated with testicular radiation and systemic chemotherapy for acute lymphoblastic leukemia with testicular relapse. He presented with recurrent dysuria and gross hematuria. Cystoscopy revealed a 2-centimeter irregular sessile mass at the bladder base adjacent to left ureteral orifice.

Purpose: To evaluate the feasibility of perineal robot-assisted laparoscopic radical prostatectomy (P-RALP) in the cadaver model.

Methods: The prostate was assessed by ultrasonography and cystoscopy in the lithotomy position. After incision and subcutaneous dissection, a single-port device was placed and the robot was docked.

Background: With the wider adoption of minimally invasive partial nephrectomy (PN), intermediate- and long-term outcomes data are needed to make firm conclusions about oncologic and functional efficacy, especially for robot-assisted PN (RPN).

Objective: To report intermediate-term oncologic and renal functional outcomes of RPN.

Design, Setting, And Participants: We performed a chart review of patients who had undergone RPN since June 2006; patients with a minimum of 2 yr of follow-up were included in this study.

Objective: To evaluate the feasibility of pure robotic natural orifice translumenal endoscopic surgery (R-NOTES) nephrectomy.

Methods: Two R-NOTES nephrectomy approaches were attempted in 3 female cadavers. A single-port device was inserted through an incision in the posterior vaginal fornix.

Objective: To assess the feasibility of robotic transrectal hybrid natural orifice translumenal endoscopic surgery (NOTES) nephrectomy and adrenalectomy.

Materials And Methods: A male cadaver was used for the present investigation and placed in lithotomy position. An 8- and 12-mm port was inserted through the same periumbilical skin incision.

Article Synopsis
  • This study analyzes data from 101 patients who underwent laparoendoscopic single-site nephroureterectomy (LESS-NU) across 15 institutions between 2008 and 2012, focusing on their demographics and surgical outcomes.
  • The average operating time was about 221 minutes, with a blood loss of approximately 232 mL; complications occurred in 10% of patients, and the average hospital stay was around 6 days.
  • The study concludes that while the early outcomes for LESS-NU are promising and comparable to standard laparoscopic techniques, further research is needed to assess the long-term effectiveness and cancer recurrence rates of the procedure.

Objective: To assess the role of family history (FH) in the risk of a positive prostate biopsy (PBx) in a large North American biopsy population as earlier reports showed increased risk of prostate cancer (PCa) in men with a FH, but the risk has been limited to low grade prostate cancer in smaller studies, and the REDUCE trial found no such risk in North American patients.

Methods: We evaluated 4360 men undergoing initial extended biopsy (8-14 cores). Indications were elevated prostate-specific antigen (PSA) and/or abnormal digital rectal examination (DRE).

Objective: To report a novel surgical approach of transvaginal hybrid natural orifice transluminal surgery (NOTES) living donor nephrectomy. We conceptualized this approach by incorporating 2 existing concepts: laparoendoscopic single-site surgery and NOTES.

Materials And Methods: After thorough consent and under institutional review board approval, a 61-year-old woman volunteered to donate her kidney through hybrid transvaginal NOTES.

Objectives: To compare the outcomes of robot-assisted laparoscopic partial nephrectomy and laparoscopic partial nephrectomy for renal tumor in patients with a solitary kidney.

Methods: We retrospectively reviewed data of patients with solitary kidney who underwent laparoscopic (n = 52) and robot-assisted (n = 15) partial nephrectomy for renal tumor at Cleveland Clinic, Cleveland, Ohio, USA, between June 2000 and April 2012. Patient demographic data, perioperative parameters and follow-up data were compared.

Purpose: We report a comparative analysis of a large series of laparoscopic and robotic partial nephrectomies performed by a high volume single surgeon at a tertiary care institution.

Materials And Methods: We retrospectively reviewed the medical charts of 500 patients treated with minimally invasive partial nephrectomy by a single surgeon between March 2002 and February 2012. Demographic and perioperative data were collected and statistically analyzed.

Background And Purpose: Ureteroneocystostomy can be used for the treatment of patients with a wide variety of ureteral pathology. Over the last decade, robot-assisted surgery has become more commonly used as a minimally invasive approach for reconstructive upper urinary tract procedures. The aim of this study is to present our experience with robot-assisted ureteroneocystosctomy (RUNC) with a comparison with that of open ureteroneocystostomy (OUNC).
