Fulltext Percutaneous renal surgery for urolithiasis

Med J Malaysia, 1990 Jun;45(2):118-22.

PMID: 2152015

Sixty eight consecutive cases of percutaneous renal surgery, percutaneous nephrolithotripsy (PCNL), were performed on 64 patients (male-41, female-23) at the Subang Jaya Medical Centre from April 1988 to July 1989. All the cases were done as a one stage procedure. Fifty eight stones were large renal or staghorn and ten were ureteric. Thirty cases (41%) were stone free after PCNL alone. Thirty eight cases had residual fragments needing extracorporeal shockwave lithotripsy (ESWL). Mean operating time was 109.6 +/- 36.0 minutes. Mean hospital stay was 4.5 +/- 1.8 days. At three months follow-up, 86% of the cases were stone free. The remaining had residual sand (less than 3mm). Minor complications occurred in six patients. None required major surgical intervention post PCNL.

PMID: 27576882

PURPOSE: To evaluate the utility and safety of laparoendoscopic single-site surgery (LESS) in comparison with conventional laparoscopic (CL) surgery for the treatment of upper urinary tract stones.

MATERIAL AND METHODS: Between June 2011 and May 2012, 20 patients with upper urinary tract stones were included in this prospective randomized study. The patients were assigned into the LESS group or CL group in a one-on-one manner using a random table. The clinical parameters were evaluated in the immediate postoperative period, and the stone clearance rate was evaluated via non-contrast computer tomography at one month postoperatively.

RESULTS: There were no significant differences in patient demographics or preoperative stone sizes between the two groups. The perioperative parameters, including operative time, estimated blood loss, postoperative pain scores, length of hospital stay, and changes in renal function, were comparable. No transfusions or open conversions were required in either group. The incidence of residual stones was lower in the LESS group (1 case) than in the CL group (2 cases). However, this difference was not statistically significant.

CONCLUSIONS: For large and impacted upper ureteral stones, the effectiveness and safety of LESS were equivalent to those of CL. Further randomized control trials with larger sample sizes are needed to strengthen the conclusions of this study.&nbsp.

Bilateral renal calculi

PMID: 4845653

Bilateral renal calculi were present in 114 (10.7%) of 1,070 cases of proved urinary calculus admitted to the Urological Department of the General Hospital, Kuala Lumpur, during the period November 1968-May 1973. The management of bilateral renal calculi is discussed with reference to the first 100 cases in this series. The introduction of renography has greatly facilitated the decision as to which kidney should be operated on first. The management of patients with and without uraemia is discussed and the use of the modified V and V-Y incisions for the removal of staghorn calculi is described. Complications and results are briefly reviewed.

Fulltext Retrograde intrarenal surgery for renal stones smaller than 2 cm

Ho CC, Hafidzul J, Praveen S, Goh EH, Bong JJ, Lee BC, et al.

Singapore Med J, 2010 Jun;51(6):512-5.

PMID: 20658113

Extracorporeal shock wave lithotripsy (ESWL) is accepted as the gold standard treatment for renal stones that are smaller than 2 cm. Recently, retrograde intrarenal surgery (RIRS) has been introduced as another form of treatment. We report our experience in dealing with renal stones smaller than 2 cm using RIRS as the primary treatment and following failed ESWL.
