“…Established risk factors for colon injury during PCNL include slim body habitus, female sex, prior colon surgery, access to the left kidney at the posterior axillary line and lower pole, and most of all a retrorenal loop of colon. [4][5][6][7][8][9]15 Other than her sex (which may not be as strong a risk factor as has been suggested, given the preponderance of male patients in the existing case reports, Table 1 3,5-9, [16][17][18][19][20][21] ) and the side of her surgery, our patient had none of these risk factors, with no evidence of retrorenal colon on her preoperative CT scan. While anatomic anomalies, such as horseshoe kidney, are associated with an increased rate of retrorenal colon, 5,22 duplication of the collecting system typically does not displace the kidney from its standard anatomic location and is unlikely to be a relevant risk factor.…”

AbstractColon perforation is a rare but serious complication of percutaneous nephrolithotomy (PCNL), meriting particular attention to its signs and symptoms for prompt diagnosis and treatment. We report an unusual presentation of colon perforation following tubeless PCNL, characterized by sore throat, pneumomediastinum, and neck and shoulder crepitus. In addition to the details of this case, we review the current literature on bowel injury during PCNL and its management.

“…(14) Total ratio of retrorenal colon was 1.7%, with 1.2% on the left side, 0.3% on the right side and 0.2% bilateral in the Atar et al study. (15) Hopper et al reported in their study based on 500 abdomen CT scans that the overall frequency of retrorenal colon was 1.9% if the images were taken in supine position. When 90 patients were studied in the prone position, retrorenal colon was found in 10%.…”

“…CT images were as previously identified. (6) to the horizontal plane a parallel line was drawn through the posterior edge of each kidney (posterior renal line) at three renal levels: upper pole, middle pole and lower pole. The number of cases with partial colon extension posterior to the posterior renal line was determined.…”

OBJECTIVE:The aim of this study was to investigate retrorenal colon incidence in percutaneous nephrolithotomy (PCNL) and to discuss the necessity of routine preoperative CT and perform a cost analysis of this procedure. MATERIALS AND METHODS: Clinical data of 608 PCNL patients over a 5 year period (2008)(2009)(2010)(2011)(2012)(2013), was surveyed. The patient files were reviewed retrospectively, and only those who had abdominal computed tomography (CT) images before PCNL intervention were included in the study. In the CT images, the position of both the ascending and descending colon in relation to the right and left kidneys were evaluated. We compared the total cost of CTs per incidence of retro colon versus the cost of restoring complications. RESULTS: According to our hospital reports, 262 patients with CT images were included in the present study. 4 patients (1.14%) had retrorenal colon, of which 2(0.76%) were on the left side, 1(0.38%) on the right side and 1(0.38%) had bilateral retrorenal colons. Colonic perforation complication was seen only in two patients who had no CT images and the colonic perforation rate was 0.57%. The cost of recognizing one retrorenal colon case using CT was cost-effective to avoid a serious complication. CONCLUSIONS: PCNL, in the process of becoming the standard treatment modality, is a safe and reliable technique for renal stone treatment. Colonic injury should be taken into consideration during PCNL interventions of the lower pole of the kidney. CT, which should be low-dose, if possible, should be performed routinely in all patients to prevent colon injuries. This technique appears to be cost-effective.

Objective The aim of this study was to investigate retrorenal colon incidence in percutaneous nephrolithotomy (PNL) interventions made in our clinic.Materials and Methods Clinical data of 804 PNL patients, accumulated over a 7 year period (2006-2012), was surveyed. The patient files were reviewed retrospectively, and only those who had abdominal computed tomography (CT) images before PNL intervention were included in the study. In the CT images, the position of both the ascending and descending colon in relation to the right and left kidneys were evaluated.Results According to our hospital reports, 394 patients with CT images were included in the present study 27 patients (6.9%) had retrorenal colon, of which 18 (4.6%) were on the left side, 4 (1.0%) on the right side and 5 (1.3%) had bilateral retrorenal colons. Colonic perforation complication was seen only in two patients and the colonic perforation rate was 0.3%. These two cases had no CT images.Conclusions PNL, in the process of becoming the standard treatment modality, is a safe and reliable technique for renal stone treatment. Colonic injury should be taken into consideration during PNL interventions of the lower pole of the kidney (especially on the left side) due to the location of retrorenal colon.

Relationship between colon and kidney: A critical point for percutaneous procedures

Abstract: In accessing the lower pole of the kidney, especially on the left side, the risk of colonic injury should be taken into consideration during percutaneous procedures, regardless of the patient's age and gender.
