Objective: The aim of this study is to assess the safety and feasibility of the transperitoneal laparoscopic approach during nephron sparing surgery in patients with previous abdominal surgery. Patients and methods: We retrospectively analyzed patients undergoing transperitoneal laparoscopic partial nephrectomy for renal masses. All patients had received a diagnosis of cT1a renal exophytic mass (⩽5 cm). Patients were divided into two groups, those with and without previous abdominal surgery. Patients with solitary kidney or major previous abdominal surgery were excluded in this study. The operative time, estimated blood loss, length of stay, surgical complications, and positive surgical margins were recorded to compare outcomes among two groups. Results: Of the 157 patients who were included in our study, 71 (45.3%) had a history of abdominal surgery (Group 1), while the remaining 86 (54.7%) had not (Group 2). Cholecystectomy was the most common previous surgery performed near the renal fossa. Patients with previous abdominal surgery experienced increased operative time (111.5 vs 83.2 min; p = 0.001). However, no statistically significant difference was found in estimated blood loss (122.1 vs 114.4 mL; p = 0.363), length of stay (4.1 vs 3.8 days; p = 0.465), rate of conversion to open surgery (2.8% vs 2.3%; p = 0.234), and rate of complications ( p = 0.121). However, operative time ( p = 0.003) and length of stay ( p < 0.001) were greater in patients with versus those without previous open cholecystectomy. Conclusion: Our results suggest that laparoscopic partial nephrectomy after minor previous abdominal surgery is safe and feasible in selected patients affected by renal masses with low nephrometry score. However, previous cholecystectomy results in an increased risk of conversion to open surgery and longer hospital stay in patients undergoing right laparoscopic partial nephrectomy.

The purpose of the present paper is to describe our technique and experience with retroperitoneal hand-assisted laparoscopic (HAL) nephrectomies as an alternative to the transperitoneal approach. Eight retroperitoneal HAL nephrectomies and one partial nephrectomy were performed. Several excisional techniques were employed incorporating the Harmonic scalpel or Ligasure device. Hemostatic agents were used to cover the renal defect. Surgical bolsters were sutured to the renal capsule with pleget reinforcements to aid in hemostasis. The average operative time was 210 min and estimated blood loss 110 mL. Mean change in hematocrit was 3 units and creatinine was 1 point. No patient required a transfusion. There were no major complications, with a mean follow-up of fourteen months. On average, patients resumed oral intake in 2 days, and were discharged in 3 days. Pathological examination revealed that two lesions were benign and seven malignant. Tumor diameter averaged 3 cm. There were no positive surgical margins. In conclusion, we have demonstrated the feasibility of retroperitoneal laparoscopic hand-assisted nephrectomy and partial nephrectomy surgery for solid renal masses.

Objectives: To evaluate oncological feasibility and oncological and functional results of retroperitoneal sutureless zero ischemia laparoscopic partial nephrectomy (LPN). Patients and methods: Patients with posterior renal masses with low nephrometry score (RENAL ≤ 7) treated who underwent retroperitoneal sutureless zero ischemia.in a single center from January 2016 to November 2017. Clinical, surgical and pathological data were prospectively collected. Complications were reported according to the modified Clavien classification. Results: Retroperitoneal sutureless zero ischemia laparoscopic partial nephrectomy was performed on 15 patients. The indication for nephron-sparing surgery was elective in 11 (73%) patients and imperative in 4 (27%). Median RENAL score was 5 (IQR: 5-7), median tumor diameter 25 mm (IQR: 20-35). In 11 cases, the tumor was located polar (85%), and in 2 cases hilar (15%). There were no intraoperative complications. No cases were converted to radical nephrectomy, and in no case parenchyma suture was necessary. Median operative time was 90 min (IQR:40-150), in no case clamping of the renal artery was necessary, median hospital stay was 4 days, median estimated blood loss (EBL) was 310 (180-500) ml. Pathological analysis showed renal cell carcinoma in 11 patients (85%), 9 (60%) staged T1a and 2 (13%) T1b. In 4 (27%) an oncocytoma was found. There were no positive surgical margins. One patient developed a major postoperative complication (postoperative renal bleeding requiring super-selective embolization). Trifecta rate was 93%. Conclusions: Sutureless retroperitoneal zero ischemia LPN for the treatment of low-complexity posterior renal masses showed to be safe and feasible. Longer follow-up and higher numbers of patients are, however, warranted to draw definitive conclusions on functional outcomes.

Abstract Purpose: To compare the trifecta outcome and perioperative and postoperative outcomes among open partial nephrectomy (OPN), laparoscopic partial nephrectomy (LPN), and robotic-assisted partial nephrectomy (RAPN) in patients with small renal masses in Ramathibodi Hospital.Methods: We retrospectively reviewed 141 patients who underwent partial nephrectomy from January 2009 to December 2018. The baseline characteristics and preoperative outcomes were compared among the three surgical approaches. Results: Among the 141 patients, 42 (29.79%), 29 (20.57%), and 70 (49.64%) patients underwent OPN, LPN, and RAPN, respectively. Among 116 patients with available data, 71 achieved the trifecta outcome [18 (56.25%), 14 (56.00%), and 39 (73.58%) in the OPN, LPN, and RAPN group, respectively; p=0.276]. The rate of conversion to OPN was higher in the LPN than RAPN group. The number of patients who received intraoperative packed red cells was lowest in the RAPN group. The estimated blood loss was significantly lower in the LPN group than OPN and RAPN groups (p=0.041). The operative time was shorter in the OPN group than LPN and RAPN groups (p<0.001). Multivariate analysis showed that the intraoperative complication rate was a predictive factor for trifecta outcome achievement.Conclusion: OPN had the shortest operative time. LPN had the highest rate of conversion to OPN and lowest estimated blood loss. The number of patients who received intraoperative packed red cells was lowest in the RAPN group. However, achievement of the trifecta outcome was not significantly different among the three groups. The predictive factor for trifecta outcome achievement was the intraoperative complication rate.

Objectives: To compare perioperative, oncological and functional outcomes of Laparoscopic Transperitoneal Partial Nephrectomy (LTPN) and Retroperitoneal Laparoscopic Partial Nephrectomy (LRPN) for posterior, cT1 renal masses (RMs). Materials and methods: Databases of two urologic institutions applying different laparoscopic surgical approaches on posterior cT1 RMs between June 2016 and November 2018 were retrospectively evaluated. Data on patient demographics, perioperative data and tumor histology were collected and further analyzed statistically. Results: Each group consisted of 15 patients. Baseline characteristics were comparable in each group. When compared to LTPN, LRPN was associated with significantly shorter operative time (OT) (115 min versus 199 min, p < 0.05). No significant differences were detected in the other outcomes. Conclusions: LRPN is associated with a significantly shorter OT compared to LTPN for posterior cT1 RMs. Both surgical approaches are safe, feasible and credible, demonstrating optimal results.

Introduction: Laparoscopic partial nephrectomy (LPN) is frequently used to manage cT1a renal masses. While data on safety and long-term oncological outcomes of LPN for T1a tumours are widely available, it is limited for >T1a lesions. We report our experience with LPN for >4 cm renal masses from a Canadian tertiary centre.Methods: Between January 2003 and July 2011, 52 consecutive LPN for >4 cm renal masses were performed. Demographic, pathological and clinical data were obtained from a prospectively maintained database.Results: The mean patient age was 60 years (62% male). Median tumour size was 4.8 (range: 4.2-11) cm. The median surgical time was 145 minutes, and the median estimated blood loss was 100 mL. The median warm ischemia time was 24 minutes. Four (7.7%) cases required conversion to open surgery. One case was converted to total nephrectomy for clinical and pathological evidence of T3 disease. The surgical margin was positive in 1 case (1.9%). Four (7.7%) patients developed a urine leak postoperatively; 3 of them managed with a ureteric stent. Four (7.7%) patients developed postoperative bleeding requiring selective angioembolization. The median hospital stay was 4 days. There was no statistically significant difference between preoperative and postoperative estimated glomerular filtration rate and mean arterial blood pressure (p = 0.5,p = 0.1, respectively).Conclusion: This series demonstrates that LPN although technically challenging has acceptable short-term surgical outcomes. Long-term assessment of oncological outcomes is required. Laparoscopic partial nephrectomy >4 cm renal tumours should not be considered a standard of care, but excellent results can be achieved in well-selected patients and in experienced hands with no impact in renal function or blood pressure.

Laparoscopic Excision

Completely endophytic renal tumours pose challenges in laparoscopic nephron-sparing tumour excisions, with the use of intraoperative imaging techniques (e.g. ultrasound) being crucial when managing such tumours. The use of a percutaneous hookwire for tumour localisations are in use in several other surgical fields, such as breast surgery. An asymptomatic 52-year-old man presented with an incidental small right sided solid 33-mm interpolar renal mass identified on computed tomography. A guided insertion of a percutaneous localisation wire was carried out prior to a laparoscopic partial nephrectomy to assist in intraoperative tumour landmark/margins identification. Operative time was 210 minutes with zero ischaemia time, with an estimated blood loss of 200 ml. No perioperative complications were observed and the patient was discharged two days postoperatively. Histology revealed the mass to be a Fuhrman grade 2 clear-cell carcinoma with a 2-mm clear surgical margin. The patient remained free of recurrence at 16 months of follow-up. We have reported our first experience of wire localisation prior to laparoscopic partial nephrectomy for an intrarenal mass, which to our knowledge could be the first of its kind in renal surgery. Percutaneous wire localisation of endophytic renal tumours is potentially safe and effective and can allow nephron-sparing surgery where laparoscopic ultrasound is not available. Longer-term and further evidence should be encouraged.

Exophytic Tumor

Renal function can be significantly preserved after nephron-sparing surgery by decreasing the intraoperative ischemic duration or by performing off-clamp surgery. We report the case of a 56-year-old woman diagnosed with a minimal-fat angiomyolipoma arising from the renal capsule, which was successfully treated by retroperitoneoscopic partial nephrectomy without hilar clamping. Computed tomography revealed a 16 × 13 mm homogenous lenticular mass protruding from the lateral aspect of the left kidney. On both T1- and T2-weighted magnetic resonance images, the mass exhibited homogenous low-signal intensity and well-defined margins. Laparoscopic magnification indicated that the exophytic tumor was attached to the renal cortex by a small peduncle. The tumor was resected completely with negative surgical margin. The estimated glomerular filtration rate after surgery was nearly equal to that before surgery. Off-clamp laparoscopic partial nephrectomy is a feasible surgical option to prevent ischemic renal damage in select patients presenting with small, exophytic, and peripheral renal masses.
